Survival motor neuron (SMN) gene: a gene for spinal muscular atrophy

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the discovery of the human survival motor-neuron gene or SMN gene which is a chromosome 5-SMA (Spinal Muscular Strophy) determining gene. The present invention further relates to the nucleotide sequence encoding the SMN gene and corresponding amino acid sequence, a vector containing the gene encoding the SMN protein or a DNA sequence corresponding to the gene and transformant strains containing the SMN gene or a DNA sequence corresponding to the gene.
More particularly, the present invention relates to means and methods for detecting motor neuron diseases having symptoms of muscular weakness with or without sensory changes such as amytrophic lateral sclerosis (ALS), spinal muscular atrophy (SMA), primary lateral sclerosis (PLS), arthrogryposis multiplex congenita (AMC), and the like. The methods for detecting such motor neuron diseases include, but are not limited to, the use of specific DNA primers in the PCR technique, the use of hybridization probes and the use of polyclonal and monoclonal antibodies.
Even more particularly, the present invention relates to the use of the human SMN gene or part of the gene, cDNA, oligonucleotide or the encoded protein or part thereof in therapy by insertion of the human SMN gene or part of the gene, cDNA, oligonucleotide or the encoded protein or part thereof, if required, into engineered viruses or vectors that serve as harmless carriers to transport the gene or part of the gene, cDNA, oligonucleotide or the encoded protein or part thereof to the body's cells including bone marrow cells.
The invention further relates to antigen sequences directed to the SMN gene.
In order to provide means for the therapy of motor neuron diseases, the invention also relates to the protein encoded by the SMN gene.
The present invention also relates to the isolation of the mouse SMN gene, the nucleotide sequence encoding the mouse SMN gene and corresponding amino acid sequence. A transgenic mouse model that hyperexpresses all or part of the SMN gene and a transgenic mouse model produced by homologous recombination with a mutated SMN gene is also described.
2. State of the Art
Degenerative motor neuron diseases can be placed into three major categories. Amyotrophic lateral sclerosis or ALS, motor neuron diseases such as spinal muscular atrophy (SMA) and motor neuron diseases associated with other degenerative disorders such as primary lateral sclerosis (PLS).
Amyotrophic lateral sclerosis (ALS) is the most frequently encountered form of progressive neuron disease and is characteristically a disorder of middle age. The disease is characterized by progressive loss of motor neurons, both in the cerebral cortex and in the anterior horns of the spinal cord, together with their homologues in some motor nuclei of the brainstem. It typically affects both upper and lower motor neurons, although variants may predominantly involve only particularly subsets of motor neurons, particularly early in the course of illness.
ALS is evidenced by the development of asymmetric weakness, with fatigue and cramping of affected muscles. The weakness is accompanied by visible wasting and atrophy of the muscles evolves and over time, more and more muscles become involved until the disorder takes on a symmetric distribution in all regions, including muscles of chewing, swallowing and movement of the face and tongue. Fifty percent of patients having ALS can be expected to die within three to five years for the onset of the disease. Presently, there is no treatment that has influence on the pathologic process of ALS.
Spinal muscular atrophies (SMA) are characterized by degeneration of anterior horn cells of the spinal cord leading to progressive symmetrical limb and trunk paralysis associated with muscular atrophy. SMA represents the second most common fatal, autosomal recessive disorder after cystic fibrosis (1out 6000 newborns). Childhood SMA is classically subdivided into three clinical groups on the basis of age of onset and clinical course. The acute form of Werdnig-Hoffmann disease (Type I) is characterized by sever generalized muscle weakness and hypotonia at birth or in the 3 months following birth. Death, from respiratory failure, usually occurs within the first two years. This disease may be distinguished from the intermediate (Type II) and juvenile (Type III, Kugelberg-Welander disease) forms. Type II children were able to sit but unable to stand or walk unaided, and they live beyond 4 years. Type III patients had proximal muscle weakness, starting after the age of two. The underlying biochemical defect remains unknown. In addition there is known to exist a slowly evolving adult form of SMA, sometimes referred to as SMA IV.
Primary lateral sclerosis (PLS) is a variant of ALS and occurs as a sporadic disease of late life. Neuropathologically in PLS there is a degeneration of the corticospinal (pyramidal) tracts, which appear almost normal at brainstem levels but become increasingly atrophic as they descent through the spinal column. The lower limbs are affected earliest and most severely.
Arthrogryposis Multiplex Congenita (AMC) is a frequent syndrome characterized by congenital joint fixation (incidence of 1 out of 3000 live births) resulting from decreased fetal movements in utero (Stern, W. G., JAMA, 81:1507-1510 (1923): Hall, J. G., Clin. Orthop., 194:44-53 (1985)). AMC has been ascribed to either oligo-hydramnios or a variety of diseases involving the central nervous system, skeletal muscle, or spinal cord. Since neuronal degeneration and neuronophagia occur in the anterior horns, it has been hypothesized that the AMC of neurogenic origin could be related to acute spinal muscular atrophy; SMA Type I Werdnig-Hoffman disease (Banker, B. Q., Hum. Pathol., (1986); 117:656-672.
The detection and clinical diagnosis for ALS, AMC, SMA and PLS is quite limited to muscle biopsies, the clinical diagnosis by a physician and electromyography (EMG). For example, the clinical criteria for diagnosing SMA is set forth in the Clinical Criteria International SMA Consortium (Munsat T. L., Neuromuscular Disorders, Vol. 1, p. 81 (1991)). but due to the complications of the various tests to detect motor neuron disorders, the clinician usually attempts to eliminate various categories of other disease states such as structural lesions, infections, intoxications, metabolic disorders and heriditary biochemical disorders prior to utilizing the above-described test methods.
Presently there is no treatment for any of the above-mentioned motor neuron disorders. Basic rehabilitative measures, including mechanical aids of various kinds, may help patients that have these diseases overcome the effects of their disabilities, but often confining respiratory support systems are necessary to have the patient survive longer.
Accordingly, it is an object of the present invention to characterize the SMN gene which is responsible for SMA disorders and to clone the SMN gene into a vector, for example a plasmid, a cosmid, a phage, a YAC vector, that can be used in the transformation process to produce large quantities of the SMN gene and SMN protein.
In yet another aspect of the invention is the use of primers and hybridization probes to detect and diagnose patients having motor neuron disorders such as AMC, ALS, SMA and PLS. Yet another aspect of the present invention is the use of SMN gene or part thereof or cDNA, oligonucleotides, protein or part thereof in therapy to correct disorders present in, for example AMC, SMA, ALS and PLS patients, especially gene disorders.
In yet another aspect, the present invention provides monoclonal and polyclonal antibodies for detection of SMN gene defects in SMA patients.
Another object of the present invention provides the characterization of the SMN gene in the mouse. A transgenic mouse model is presented that hyperexpresses all or part of the SMN gene or a transgenic mouse that by homologous recombination with a mutated mouse SMN gene produces abnormalities in the SMN gene is also described.
According to a further aspect of the invention, the therapy of motor neuron diseases can involve the protein encoded by the SMN gene.
These and other objects are achieved by the present invention as evidenced by the summary of the invention, the description of the preferred embodiments and the claims.
OBJECTS AND SUMMARY OF THE INVENTION
It is an object of the present invention to provide a novel human Survival Motor Neuron gene or SMN gene, its DNA sequence and amino acid sequence.
Another aspect of the present invention provides a novel mouse Survival Motor Neuron gene or SMN gene, its DNA sequence and amino acid sequence.
Yet another aspect of the present invention is the provision of a vector which is capable of replicating in a host microorganism to provide large quantities of the human or mouse SMN protein.
Yet another aspect of the present invention is the provision of specific DNA sequences that can be used to detect and diagnose spinal muscular atrophy and other motor neuron disorders. These DNA sequences can be used as primers in the polymerase chain reaction to amplify and detect the SMN gene sequence, a truncated or mutated version of the SMN gene sequence or lack of said sequence which leads to the diagnosis of SMA, AMC, and other motor neuron disorders.
Yet another aspect of the present invention provides a transgenic mouse that hyperexpresses all or part of the SMN gene or a transgenic mouse that by homologous recombination with a mutated mouse SMN gene produces abnormalities in the SMN gene is also described.
The inventors have identified two genes respectively designated T-BCD541 and C-BCD541, which are involved in motor neuron disorders.
The T-BCD541 gene is responsible for the motor neuron diseases of the SMA type, since its alteration either by partial or total deletion, by mutation or any other modification, is sufficient to lead to a pathological state at the clinical electromyographic or muscle morphological levels.
The C-BCD541 gene is different from the T-BCD541 gene, at the level of the cDNA, since two nucleotides are modified. This C-BCD541 gene is nevertheless not correctly processed during the transcription in controls and patients suffering from motor neuron diseases. The genomic DNA of the C-BCD541 gene is not correctly spliced during the transcription providing thus for an abnormal transcript. The difference between the splicing of the T-BCD541 and the C-BCD541 gene results from differences in the sequence of the introns of these genes.
The present invention thus further characterizes the structure and organization of the human SMN gene which was found to be approximately 20 kb in length and consists of 9 exons interrupted by 8 introns. The nucleotide sequence, amino acid sequence as well as the exon-intron boundaries of the human SMN gene is set forth in FIG. 10. All exon-intron boundaries display the consensus sequence found in other human genes. A polyadenylation consensus site is localized about 550 bp downstream from the stop condon (FIG. 10). The entire intron/exon structure of the SMN gene permits the characterizations of the SMN gene mutations in SMA disease or other motor neuron diseases.
The present invention also defines means for the detection of genomic abnormalities relating to motor neutron diseases at the level of the T-BCD541 gene or at the level of the C-BCD541 gene.
The genes of the invention can be further defined in that each of them comprise intronic sequences corresponding to the following sequences:

In a preferred embodiment of the invention, the gene of the invention is capable of hybridizing in stringent conditions with the sequence of FIG. 3 (SEQ ID NOS: 12-13) used as probe.
As hereabove written, the invention further relates to a variant of the SMN gene, which variant is a C-BCD541 gene having a cDNA sequence corresponding to the sequence of FIG. 2 (SEQ ID NOS: 10-11).
The invention also relates to cDNA sequences such as obtained from one of the above genes. Such cDNA sequences are disclosed in FIGS. 2 and 3. Both of these cDNA sequence are capable of encoding a protein comprising the amino acid sequence described in FIG. 1 (SEQ ID NO: 9).
Despite this capacity to encode for such a protein, the inventors have noted that the C-BCD541 gene is not able to produce in vivo this protein or is not able to produce it in a sufficient quantity due to the abnormal splicing of the gene during the transcription. Thus, the presence of the C-BCD541 gene does not enable to correct in vivo the deficiency (deletion, mutation, . . . ) of the T-BCD541 gene responsible for the motor neuron diseases of the SMA type or other motor neuron disorders.
In a particular embodiment, the invention relates also to a nucleotide sequence comprising nucleotides 34 to 915 of the sequence of FIG. 3, or to a sequence comprising nucleotides 34 to 915 of the sequence of FIG. 2.
These nucleotide sequences correspond to the coding sequence of respectively the T-BCD541 gene and C-BCD541 gene.
The introns of the hereabove described genes are also included in the application. Especially introns 6 and 7 have respectively the following sequences:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
As used herein, the term "contig" means overlapping nucleotide sequences.
Previous studies by means of linkagee analysis have shown that all three forms of spinal muscular atrophy map to chromosome 5q11.2-q13.3. (L. M. Brzustowicz et al, Nature, 344, 540 (1990); J. Melki et al, Nature, 345, 823 (1990); J. Melki et al, Lancet, 336, 271 (1990). A yeast artificial chromosome (YAC) contig of the 5q13 region spanning the disease locus was constructed that showed the presence of low copy-repeats in this region. Allele segregation was analyzed at the closest genetic loci detected by markers derived from the YAC contig (C212, C272 and C161) in 201 SMA families. These markers revealed two loci (C212, C272) or three loci on the 5q13 region (C161). Inherited and de novo deletions were observed in 9 unrelated SMA patients. Moreover, deletions were strongly suggested in at least 18% of SMA type I patients by the observation of marked heterozygosity deficiency for the loci studied. These results indicated that deletion events are statistically associated with the sever form of SMA.
By studying all polymorphic DNA markers derived from the YAC contig, it was observed that the smallest rearrangement occured within a region bordered by loci detected by C161 and C212-C272 and entirely contained in a 1.2-Mb YAC clone 903D1. See, for example, French Patent Application No. 9406856 incorporated herein by reference.
The present invention characterized the small nested critical SMA region of about 140 Kb by a combination of genetic and physical mapping in SMA patients. This region suggested a precise location for the SMA gene and therefore, as limited region within which to search for candidate genes. The present invention identified a duplicated gene from the 5q13 region. One of them (the telomeric gene) is localized within the critical region. Moreover, this gene was lacking in 213 out of 230 (92.2%) or interrupted in 13 out of 230 (5.6%) SMA patients. In patients where the telomeric gene is not lacking or interrupted, deleterious mutations indicated that this telomeric gene, termed survival motor-neuron (SMN) gene, is the chromosome 5 SMA-determining gene.
The SMN gene was discovered using a complex system of restriction mapping, distinguishing the E.sup.Tel from the E.sup.Cen by Southern blot, and the determination of the differences between the E.sup.Tel in SMA patients by genetic and physical mapping. After confirming the location of the SMN gene, a phage contig spanning the critical region of the telomeric element was constructed to identify specific clones containing the SMN gene.
Analysis of the SMN gene in SMA patients compared with those of normal patients revealed either the SMN gene was either lacking or truncated in 98% of SMA patients or had combined mutations not present in normal control patients.
To identify a large inverted duplication and a complex genomic organisation of the 5q13 region, long-range restriction mapping using pulsed field gel electrophoresis (PFGE) of the YAC contig was performed.
YACs were ordered by comparing their haplotypes with that of the human donor at the polymorphic loci detected markers C212, C272, C171 C161 (FIG. 4 (SEQ ID NOS: 14-18).
The restriction enzymes SacII, BssHII, SfiI, EagI and XhoI were used to digest the YACs containing the telomeric loci detected by markers C212, C272, C171 and C161 (YAC clone 595C11), the centromeric loci detected by these markers (YAC clones 121B8, 759A3, 278G7) or both *YAC clones 903D1 and 920C9). Lambda phage libraries of YACs 595C11, 121B8 and 903D1 were constructed and subclones from phages containing markers C212 (p322), C272 (132SE11), C161(He3), AFM157xd10(131xb4) and CMS1 (p11M1) were used as probes for PFGE analysis. FIG. 5 shows that probes 132SE11, 11P1 and p322 revealed two loci, and probe He3 revealed 4 loci on the YAC contig, whereas probe 13xb4 revealed several loci on 5p and 5q13. The restriction map (FIG. 6) showed that the 5q13 region contained a large inverted duplication of an element (E) of at least 500 Kb, termed E.sup.Tel and E.sup.Cen for the telomeric and centromeric elements, respectively.
The PFGE analysis of SMA an control individuals revealed a high degree of variability of restriction fragments which hampered the distinghishment of E.sup.Tel from the E.sup.Cen and the recognition of abnormal restriction fragments in SMA patients.
In order to distinguish between the E.sup.Tel and the E.sup.Cen, a Southern blot analysis was then performed. The Southern blot was performed by the methods described in Sambrook et al, supra.
More specifically, DNA from YAC clones, controls and SMA patients was digested with restriction enzymes SacI, KpnI, MspI, PstI, PvuII, EcrRI, HindIII, BgIII and XbaI for Southern blotting and hybridized with clones 132SE11, 11p1, He3, 131xb4 and p322 as probes. None of the probes except one (He3) detected a difference between the two duplicated elements. Three HindIII restriction fragments of 12, 11 and 3.7 Kb were detected by probe He3. A 12 Kb HindIII restriction fragment was detected in YAC clones 754H5 and 759A3, indicating that this fragment corresponded to the most centromeric locus in the E.sup.Cen. Conversely, a 11 Kb HindIII fragment was detected in YACs clones 595C11, 903D1 and 920C9 indicating that this fragment corresponded to a single locus on the E.sup.Tel. Finally, a 3.7 Kb HindIII fragment was noted in non-overlapping YACs containing either E.sup.Tel or E.sup.Con, indicating that this fragment corresponded to two different loci. Similar results were obtained with SacI and KpnI. The three restriction fragments detected by He3 were observed on the monochromosomal hybrid HHW105 (Carlock, L. R. et al, Am. J. of Human Genet., 1985, Vol 37, p. 839) and in 30 unrelated, healthy individuals, confirming that these fragments were not due to polymorphisms. The Southern analysis results allowed one to distinguish E.sup.Tel from the E.sup.Cen in both controls and SMA patients.
Thus, once the E.sup.Tel from the E.sup.Cen was distinguished, it was necessary to determine the difference between the E.sup.Tel in SMA patients and those of the normal control. This was done by using genetic and physical mapping. This genetic and physical mapping identified genomic rearrangements in the telomeric element of E.sup.Tel of SMA patients.
It was previously shown that 9 out of 201 (9/201) SMA patients displayed large-scale deletions encompassing either one or the two loci detected by markers C212 and C272 on one mutant chromosome (J. Melki et al, Science, 264, 1474 (1994)). On the other hand, 22 out of 30 (22/30) patients born to consanguineous parents including 13 out of 14 (13/14) type I and 9 out of 10 (9/10) type III SMA, were homozygous by descent for the most closely flanking polymorphic markers.
The genomic DNA of the 9 patients harboring large scale deletions and the 22 consanguineous patients displaying homozygosity by descent were digested with HindIII for Southern blotting and hybridized with probe He3. The 11 Kb fragment revealed by probe He3 was absent in 12 out of 13 (12/13) consanguineous type I patients. In 2 out of 12 (2/12), the deletion also involved the 3.7 Kb fragment. By contrast, the 11 Kb fragment was absent in 1 out of 8 (1/8) consanguineous type III patients only. Consistently, the 11 Kb HindIII fragment was absent in 4 out of 9 (4/9) patients harboring large scale deletions on one mutant chromosome. Of particular interest was the absence of the 11 Kb fragment in the patient harboring a deletion of one of the two loci detected by markers C212 and C272.
When analyzed together, these observations provided evidence for genomic rearrangements of E.sup.Tel in SMA patients and supported the location of the SMA gene centromeric to the locus revealed by the 11 Kb HindIII fragment, since all consanguineous type III patients but one were not deleted for this locus.
In order to characterize the centromeric boundary of the genomic rearrangement in the disease, the allele segregation at loci detected by marker C272 in consanguineous SMA patients was analyzed. All consanguineous SMA type I patients had one single PCR amplification product, compared with 0 out of 60 controls. This marked heterozygosity deficiency was due to deletion of one of the two loci detected by C272, as indicated by the marked decrease of gene dosage with probe 132SE11, mapping close to this marker. By constrast, 7 out of 9 (7/9) consanguineous type III SMA patients had two C272 amplification products inherited from both parents, indicating homozygosity at each locus detected by marker C272. Moreover, no gene dosage effect was observed with probe 132SE11 indicating the absence of deletion involving the locus detected by C272 in type III consanguineous patients.
Assuming that the same locus is involved in all three types of SMA, these results indicate that the disease causing gene is distal to the telomeric locus detected by C272.
These studies place the SMA gene within the telomeric element E.sup.Tel, between the telomeric loci detected by markers C272 and He3 (11 kb HindIII fragment). Based on long-range restriction mapping using PGFE of the YAC contig, this critical region is entirely contained in a 140 kb SacII fragment of YAC clone 903D1 (or 150 Kb SacII fragment of YAC clone 920D9).
After confirming that the SMN gene was located on a 140 Kb SacII fragment a phage contig spanning the critical region of the telomeric element was constructed in order to identify and characterize the SMN gene.
Phage clones containing markers C212, C272, C171 and C161 were isolated from the .lambda. phage libraries constructed from YAC clones 595C11 and 903D1 and used as a starting point for bidirectional walking. A phage contig (60 Kb) surrounding markers C212, C272 and C171 was constructed based on the restriction map of the phage clones (FIG. 6).
To identify genes in the contig, the following three strategies were used:
1) a search for interspecies conserved sequences was conducted;
2) exon trapping method was performed; and
3) direct cDNA selection was performed. The genomic probe 132SE11, derived from the phage containing the marker C272, gave positive hybridization signals with hamster DNA indicating the presence of interspecies-conserved sequences. The screening of a .lambda.gt10 human fetal brain cDNA library with probe 132SE11 resulted in the selection of 7 overlapping .lambda. clones spanning 1.6 kbp. Sequence analysis of the clones revealed a 882 bp open-reading frame (ORF) and a 580 bp non-coding region. A 1.5 kbp clone (BCD541) contained the entire coding sequence and most of the 3' non-coding region. The 3' end of the cDNA along with its poly(A).sup.+ tail was obtained by PCR-amplification of a lymphoblastoid cell line cDNA library.
Two cDNA clones lacked nucleotides 661 to 755, suggesting that an alternative splicing might have occured. Northern blot analysis of poly(A).sup.+ RNA from various tissues including heart, brain, liver, muscle, lung, kidney and pancreas, revealed the presence of a widely expressed 1.7 kb transcript. The ORF encodes a putative protein of 294 amino acids with a predicted molecular weight of approximately 32 Kd.
A homology search using the FASTA and BLAST networks failed to detect any homology at either the nucleotide or the amino acid level.
To further distinguish whether there was any duplication of the BCD541 gene in the 5q13 region, BCD541 cDNA was used as a probe for Southern blot and PFGE analysis of YAC clones spanning the disease locus.
Specific hybridization with non-overlapping YACs containing either the E.sub.Cen only (YAC clones 759A3, 121B8 and 278G7), or containing the E.sup.Tel only (YAC clone 595C11) provided evidence for duplication of the BCD541 gene. Each gene encompassed approximately 20 kb and displayed an identical restriction pattern. Evidence for head to head orientation of the two genes was derived from the location of the SacII and EagI restriction sites of the non-overlapping YAC clones containing either E.sup.Cen or E.sup.Tel, following hybridization experiments with probes BCD541 and p322 which flank the SacII and EagI sites of each element.
In order to look for divergences in the two copies of the BCD541 gene, the organization of the telomeric gene was characterized and compared to that of the centromeric counterpart. Genomic sequence analysis revealed that the telomeric BCD541 gene is composed of 8 exons (FIG. 3). However, it is now known that the previously known exon 2 is composed of 2 exons separated by an additional intron as set forth in FIG. 10, therefore the SMN gene is composed of 9 exons.
Starting from either the centromeric or telomeric gene loci (in YAC clones 121B8 and 595C11, respectively), PCR-amplification and sequence of each exon and their flanking regions revealed five discrepancies between the centromeric and the telomeric BCD541 genes. The first one is a conservative substitution in exon 7 (condon 280) specific for the telomeric (TTC) or the centromeric BCD541 gene (TTT). The second one, located in the 3' non-coding region (exon 8 nucleotide n.degree. 1155) is specific for the telomeric (TGG) or the centromeric BCD541 gene (TGA). Three other single base substitutions were observed in the sixth and seventh introns.
The observation of both versions of each exon (exon 7 and 8) on either YAC clones containing both gene loci (YAC clone 920C9) or the monochromosomal hybrid HIIW105 demonstrated that these substitutions are neither allelic nor due to polymorphisms. Band shifts on SSCP analysis of amplified exons 7 and 8 allowed an easy distinction of the telomeric (T-BCD541) and centromeric genes (C-BCD541) in both controls and SMA patients. All the unrelated healthy controls tested (n=75) harbored the T-BCD541 gene as determined by SSCP analysis of exons 7 and 8 (100%). Most of them (89.3%) also harbored the C-BCD541 gene but 8 out of 75 (8/75) (10.7%) lacked the C-BCD541.
A total of 230 SMA patients were tested for single base substitutions detected in exons 7 and 8 by SSCP method after PCR-amplification of genomic DNA. Among them, 103 belonged to type I, 91 to type II, and 36 to type III. Interestingly, 213 out of 230 SMA patients (92.6%) lacked the T-BCD541 gene on both mutant chromosomes compared with 0 out of 75 controls (0%). Moreover, 13 out of 230 SMA patients (5.6%) lacked the T-BCD541 gene for exon 7 on both mutant chromosomes but retained the T-BCD541 gene for exon 8 compared with 0 out of 75 controls (0%). Finally, only 4 out of 230 SMA patients (1.7%) harbored the T-BCD541 gene as determined by SSCP analysis of exons 7 and 8.
These results show that the T-BCD541 gene is either lacking or truncated in 98% of SMA patients. In addition, these data support the view that the disease gene is located between the telomeric locus detected by C272 and exon 8 of the T-BCD541 gene. Therefore, according to the overlapping restriction map of the phage contig, the critical region is entirely contained in 20 kb, suggesting that the telomeric T-BCD541 gene is the chromosome 5 SMA-determining gene.
In order to demonstrate that the T-BCD541 gene is responsible for SMA, point mutations in the 4 SMA patients in whom no rearrangement of the T-BCD541 gene had been observed were searched. Direct sequencing of PCR amplification products of each exon with their flanking regions was performed in the four patients.
A 7 bp deletion in the 3' splice acceptor site of intron 6 (polypyrimidine tract) was found in patient SA. Sequence analysis of exon 7 flanking the deleted intron, recognized the sequence specific for the T-BCD541 gene. Moreover, the non-delected PCR-product corresponding to the same region, harbored the sequence specific for the T-BCD541 suggesting that the other mutant allele lacked the T-BCD541 gene.
In patient BI, a 4 bp deletion in the 5' consensus splice donor site of intro 7 was found. This deletion occured on the T-BCD541 gene as determined by sequence analysis of the flanking exon 7.
In patient HU, a point mutation in codon 272 (TAT.fwdarw.TGT) was found. This mutation changed a Tyrosine to Cysteine. The patient was heterozygous for the mutation, presumably carrying a different SMA mutation on the other allele. All three mutations observed in patients SA, HU and BI were not detected in 100 normal chromosomes ruling out rare polymorphisms.
A different splicing of exon 7 distinguished the C-BCD541 from the T-BCD541 gene using reverse transcription-based PCR. Eleven SMA patients were selected for the analysis of their transcipts by Northern blot or reverse transciption-based PCR amplification. Eight of them belonged to type I, 1 to type II and 2 to type III. SSCP analysis of genomic DNA showed an absence of T-BCD541 gene in 10 patients and one patient (SA) had C-BCD541 and T-BCD541 genes for both exons 7 and 8. Six unrelated controls who harbored both C-BCD541 and T-BCD541 genes and 2 controls with only T-BCD541 gene were included in the present study.
The expression of this gene in lymphoblasts made it possible to analyze the BCD541 transcripts in cell lines derived from controls and SMA patients. Northern blot analysis of RNA from lymphoblastoid cell lines showed the presence of a 1.7 kb mRNA in all samples. None of the SMA patients showed a transcript of altered size. It was observed that a reduced level of transcripts was obtained when compared to the expression of the .beta.-actine gene in 3 out of 4 type I SMA patients. Normal mRNA level were found for the other SMA probands.
Since the Northern blot analysis revealed the presence of a transcript in SMA patient who had the C-BCD541 gene only for both exons 7 and 8 as determined by SSCP analysis, these results indicated that both C-BCD541 and T-BCD541 genes were expressed. To prove whether both BCD541 genes were expressed, RT-based PCR amplification of RNA isolated from the lymphoblastoid cell lines from controls and SMA patients was used. Direct sequencing of PCR products flanking exons 7 and 8 revealed that patients who had C-BCD541 only displayed the sequence specific for the C-BCD541 gene. Controls who had both T-BCD541 and C-BCD541 genes, had two types of transcipts corresponding to both BCD541 genes. These results confirmed that both genes were expressed. In addition, 2 alternative splicings involving exon 5 or exon 7 that results in different transcripts were observed. The alternative splicing of exon 5 confirmed previous sequence data on the cDNA clones.
The analysis of the RT-PCR amplification products encompassing exons 6 to 8 showed that the spliced transcript keeping exon 7, was present in controls who had both C-BCD541 and T-BCD541 genes or controls who had the T-BCD541 gene only. Conversely, the alternative spliced transcript lacking exon 7 was observed in controls who had both genes, but not in controls who had the T-BCD541 gene only. These results indicated that the alternative spliced transcript lacking exon 7 was derived from the C-BCD541 gene only.
The transcript analysis of patient SA harboring a 7 bp deletion of the 3' splice acceptor site of intron 6 of the T-BCD541 gene revealed the presence of both spliced transcript keeping exon 7 and alternate spliced transcript lacking exon 7. Moreover, the sequence analysis of amplification products from the spliced transcript keeping exon 7, showed a sequence specific for the C-BCD541 gene (FIG. 2). These results demonstrated that the 7 bp deletion of intron 6 observed in patient SA was deleterious for the correct splicing of exon 7 of T-BCD541 gene only. In addition, because a differential splicing of exon 7 allowed one to distinguish the 2 BCD541 genes, this difference was analyzed among controls and SMA patients including patient SA. In controls, the amount of alternated spliced transcript lacking exon 7 was less abundant than that of spliced product keeping exon 7. Conversely, in SMA patients, the amount of alternated spliced transcript lacking exon 7 was equal or more abundant than that of spliced product keeping exon 7.
These results provide evidence for a difference between controls and SMA patients at the transcription level of these genes. The alternative spliced transcript lacking exon 7 resulted in a shorter ORF with a different C-terminus protein that might have effects on the protein function.
To further characterize the entire structure and organization of the human SMN gene, three genomic clones were isolated from a FIX II phage library derived from YAC clone 595C11 and screened with the full-length BCD541 cDNA (FIG. 2A) as a probe. After selecting several clones that hybridized to the probe, restriction mapping and Southern blot analysis indicated that phages L-132, L-5 and L-13 spanned the entire SMN gene.
These three phage clones were further subjected to sequencing using the Maxam-Gilbert or Sanger et al methods of sequencing disclosed in Sambrook et al supra.
The nucleotide and amino acid sequence of the entire SMN gene including exons and introns is set forth in FIG. 10. The human gene is approximately 20 kb in length and consists of nine (9) exons interrupted by 8 introns as shown in FIG. 10. The human SMN gene has a molecular weight of approximately 32 kDA.
Although it was thought that only one exon 2 was present in the SMN gene (see, Lefebvre et al, Cell, 80:155-165 (1995)), the sequencing data proved otherwise and the previously mentioned exon 2 in Lefebvre et al supra is in fact composed of 2 exons separated by an additional intron, as illustrated in FIGS. 9 and 10. To avoid confusion in the renumbering of exons, the 2 exons in exon 2 are now referred to as exon 2a and exon 2b.
All exon-intron bounderies displayed the consensus sequence found in other human genes and a polyadenylation consensus site is localized 550 bp downstream from the stop codon (FIG. 10).
Starting from either YAC clones 121B8 or 595C11 (which contain the C-BCD541 and SMN genes respectively, (see, Lefebvre et al, supra) PCR amplification and sequence analysis of the introns showed three differences between SMN and C-BCD541 in addition to those previously described (by Lefebvre et al, supra). These included a base charge in intro 6 (-45 bp/exon 7, atgt, telomeric, atat, centromeric) and two changes in intron 7 (+100 bp/exon 7, ttaa, telomeric; ttag, centromeric and at position +214 bp/exon 7, ttat, telomeric; ttgt, centromeric, FIG. 10). The presence of both versions in a YAC clone containing both genes (YAC 920C9), and in the control population demonstrated that these substitutions are locus-specific rather than due to polymorphism. Band shifts on single strand conformation polymorphism (SSCP) analysis of the PCR amplified intron 7 allowed SMN and its centromeric counterpart (C-BCD541) to be readily distinguished (see, FIG. 15).
In order to identify sequences potentially important for promoter function, the organization of the region surrounding exon 1 of the SMN and C-BCD541 genes was characterized. Based on restriction mapping, Southern blot hybridization and PCR amplification, exon 1 and the C272 marker (D5F150S1, D5F150S2) were located in the same BgIII-EcoRI restriction fragment of L-132 phage (FIG. 9). PCR amplification using the C272f primer and a reverse primer chosen in exon 1 was performed and the amplified product was directly sequenced. Sequence analysis showed that the (CA) repeat corresponding to the C272 marker are located 463 bp upstream from the putative ATG translation start site (FIG. 11). Comparative sequence analyses showed no discrepancy between the 5' ends of the SMN gene and its centromeric counterpart (C-BCD541). In addition, sequence analysis showed the presence of putative binding sites for the following transcription factors: AP-2, GH-CSE2, DTF-1, E4F1, HiNF-A, H4TF-1, .beta.-IFN, Sp1 (FIG. 11; Faisst et al, Nucleic Acids Res., 20:3-26 (1992)).
Besides isolating and characterizing the human SMN gene, the mouse homologue of the SMN gene was also cloned. Cross-species conservation of human SMN gene with rodents has been shown in Lefebvre et al, supra and served to isolate the mouse SMN gene. Screening of a mouse fetal cDNA library using human SMN cDNA as a probe allowed the isolation of 2 overlapping mouse cDNA clones. Sequences analysis of the clones revealed an 864 bp open-reading frame (ORF) (FIG. 12). The ORF encodes a putative protein of 288 amino acids (FIG. 12) with an homology of 83% with human SMN amino acid sequence (FIG. 13).
Either the isolated human or the mouse SMN, the gene can be inserted into various plasmids such as pUC18, pBr322, pUC100, .lambda.gHI, .lambda.18-23, .lambda.ZAP, .lambda.ORF8, and the like. The methods for inserting genes into different plasmid vectors are described by Sambrook et al supra. Various microorganisms can be used to transform the vector to produce the SMN gene. For example, host microorganisms include, but are not limited to, yeast, CHO cells, E. coli, Bacillus subtilis and the like.
Once recombinantly produced, the human SMN protein or the mouse SMN protein can be further purified from the host culture by methods known in the art.
Besides recombinantly producing the SMN protein, the present invention also relates to the production of polyclonal and monoclonal antibodies. These methods are known in the art as evidenced by Sambrook et al supra. The monoclonal antibody can be obtained by the procedure of Kohler and Milstein, Nature, 256:495 (1975); Eur. J. Immunol., 6:511 (1976) or Harlow and Lane Antibodies, a Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, New York (1988), and can be used, for example, in diagnosing SMA, as well as other motor neuron disorders.
Polyclonal rabbit antisera can also be generated against synthetic peptides corresponding to any part of the SMN amino acid sequence including the amino terminus and carboxy terminus. More specifically, the following peptides were synthesized based on the amino acid sequence set forth in FIG. 1:
N-terminal G G V P E Q E D S V L F R R G T (residues 9-25 of SEQ IDNO:9) C-terminal S R S P G N K S D N I K P K (residues 173-186 of SEQ IDNO:9) F R Q N Q K E G R C S H S L N (residues 200-294 of SEQ IDNO:9)
The synthetic peptide may be coupled to a carrier protein such as Keyhole limpet hemocyanin (KLH) through an amino- or carboxy-artificial cysteine residue that may be synthetically added to the desired sequence. The cysteine residue is used as a linker to couple the synthetic peptide to the carrier protein. The procedure utilized to couple synthetic peptides to KLH is described by Green et at, Cell, 28:477 (1982).
Approximately, 50-100 .mu.g, preferably 100 .mu.g of synthetic antigen is dissolved in buffer and emulsified with an equal volume of Freund's complete adjuvant. About 0.025 ml to 0.5 ml of emulsified antigen-adjuvant can be injected intramuscularly or intradermaly into a rabbit. Four to six weeks later, the rabbit is boosted and 20-40 ml of blood is drawn 7-10 days after each booster injection. The serum is then tested for the presence of antigen using RIA, ELISA or immunoprecipitation. The positive antibody fractions may then be purified, for example by absorption to protein A following the method of Goudswaald et al, Scand. J. Immunol., 8:21 (1978).
More specifically, about 20 to 50 .mu.g of antigen, prepared either by the recombinant techniques set forth above or synthetically made antigen is diluted in about 100 .mu.l of buffer and emulsified with an equal amount of Freund's complete adjuvant. About 30-60, preferably 50 .mu.l of the emulsified antigen-adjuvant is injected subcutaneously at four sites into mice. Four to six weeks later, the mice are boosted with an intraperitoneal injection of about 100 .mu.l containing 5-10 .mu.g of antigen solubilized in buffer. The mice are bled from the mediam tail vein 7-10 days after the boaster injection and the serum is tested for antibody using standard methods. Blood is then drawn every 3-4 days until the antibody titer drops.
Tissue, plasma, serum, cerebral spinal fluid and the like can be used to detect SMA disease using the above-described monoclonal or polyclonal antibodies via Western blot (1 or 2 dimensional) or ELISA. These methods are known in the art as described by Sambrook et al, supra.
A method for detecting SMA as well as in ALS, ACM, and PLS patients who possibly have these motor neuron disorders, is also encompassed by the present invention. This method involves extracting from a patient suspected of having SMA, DNA from a sample. This sample may include sera, plasma, cerebral spinal fluid and the like. After extracting the DNA by known methods in the art, primers that are derived from exons 7 and 8 of the SMN gene are used to amplify the DNA.
After amplification with the primer, the amplified product is subjected to SSCP (Single Strand Conformation Polymorphism).
The gels are then subjected to autoradiography to determine if SMA is present in the sample.
More specifically, it has recently been discovered that in twelve cases of arthrogryposis multiplex congenita (AMC) associated with SMA, 6 out of 12 patients lacked the SMN gene.
A total of twelve unrelated patients including eight males and four females of various geographic origins was selected for the study. The patients were chosen based on the criteria that these patients had:
(1) congenital joint contractures of at least two regions of the body (see, Stern, JAMA, 81:1507-1510 (1923));
(2) generalized muscle weakness with muscular atrophy and are flexia without extraocular involvement;
(3) electromyographic studies showed denervation and diminished motor action potential amplitude; and
(4) muscle biopsies consistent with denervation with no evidence of storage material or other structural abnormalities (see, Munsat, Neuromuscular Disorders, 1:81 (1991)).
The study consisted of Dinucleotide Repeat Polymorphism Analysis and SMN gene analysis (see, Examples) based on DNA extracted from peripheral blood leukocytes, lymphoblastoid cell lines or muscle tissue in all twelve patients.
The data from this study is summarized in Table 1 below.
The diagnosis was made at birth with an uniform phenotype characterized by a severe hypotonia, absence of movements except extraocular mobility and contractures of at least two joints. The number of affected joints and the severity of the postural defects varied from infant to infant, as set forth in Table 1. Decreased fetal movements were noted in 7 out of 12 (7/12) patients. Neonatal respiratory distress was observed in 9 out of 12 (9/12) patients and facial involvement associated with micrognathia was noted in 4 out of 12 (4/12) patients. Most of the cases, 8 out of 12 (8/12), died within the first month of life. Four infants are still alive. No family history was noted except in family 12 in which both the child and her father were affected suggesting an autosomal dominant form of AMC.
Table 1 shows that the SMN gene was lacking on both mutant chromosomes in 6 out of 12 (6/12) patients (cases 1-6). Among them, 3 out of 6 (3/6) patients had a large inherited deletion involving both loci detected by markers C212 and C272 on one parental allele, the other parental carrying only one locus instead of the expected two, as shown in FIG. 14.
Analysis of SMN exons did not reveal intragenic mutations in the patients whose SMN gene showed no deletions (cases 7-12). Genetic analysis showed that the disease gene in a family (case 9) was not linked to chromosome 5q13 as both the affected and healthy siblings carried the same 5q13 haplotype. These data strongly suggest that the patients whose SMN gene showed no deletions were not linked to the 5q13 SMA locus (cases 7-12).
Hithto, arthrogryposis was regarded as an exclusion criterion in SMA (see, Munsat, supra). But the observation of SMN gene deletion in 6 out of 12 (6/12) patients (50%) strongly indicates that arthrogryposis of neurogenic origin is related to SMA and that this subgroup and SMA are allelic disorders. Yet, AMC of neurogenic origin is a genetically heterogeneous condition since the disease gene was not linked to SMN locus in 6 out of 12 (6/12) patients. Exclusion of chromosome 5q has also been shown in one family with two AMC-SMA patients, as described by Lunt et al, J. Med. Genet., 29:273 (Abstract) (1992).
Thus, by dinucleotide Repeat Polymorphism Analysis and SMN gene analysis, clinical diagnosis of AMC can be confirmed by the absence or interruption of the SMN gene. The present invention now provides methods to detect AMC either in live patients or in utero.
Yet another embodiment of the present invention is the detection of SMA using specific oligonucleotide probes based on the nucleotide sequence set forth in FIGS. 3, 10, or for the mouse SMA FIG. 12. If a patient totally is lacking in the SMN gene, no hybridization to the specific probe will occur. The hybridization conditions may vary depending upon the type of sample utilized. It is preferable to conduct such hybridization analysis under stringent conditions which are known in the art and defined in Sambrook et al supra. The oligonucleotide probes may be labeled in any manner such as with enzymes, radioactivity and the like. It is preferable to use radiolabeled probes.
In another embodiment of the present invention, the human SMN gene can be utilized in conjunction with a viral or non-viral vector for administration in vivo directly to the patients suffering from SMA or related motor neuron diseases or by administration in vitro in bone marrow cells, epithelial cells fibroplasts, followed by administration to the patient. See, for example Resenfeld et al, Science (1991) 252, pp. 431 to 434.
The present invention provides a method of detecting SMN gene defects or the total lack of the SMN gene in a fetus. Amniotic fluid taken from the pregnant woman is subjected to SSCP analysis according to the methods of the present invention.
In order to further illustrate the present invention and advantages thereof, the following specific examples are given, it being understood that the same are intended only as illustration and in nowise limitative.
