Progress in science and technology with shifting epidemiology and demographics are creating the capabilities and demand for alternatives to symptom-driven medical models. Reducing age-related chronic diseases associated with premature mortality among adults is an urgent priority requiring new approaches and technologies.
The near-doubling of average human life expectancy over the last 150 years is a tribute to scientific advancements in medicine and public health. Most of this success—though not all—is the result of progress in control and prevention of infectious diseases particularly among young children. Eighty-five percent of children born now in the US are expected to live to 65 years of age; at least 42% will likely celebrate an 85th birthday. Because of these successes most of humanity is facing a daunting and costly new medical challenge in the form of age-related chronic diseases.
Most age-related chronic diseases have heritability, are often slowly progressive with symptom-free onset, and are associated with common risk factors. In 2015, the estimated US cumulative mortality risk among males 50 to 74 years of age was 39%; for women, the risk was lower but still substantial at 24%. The causes of these deaths are similar across genders with neoplasms and cardiovascular disease accounting for about one-third each, and diabetes and related conditions, respiratory, cirrhosis and other liver diseases, and neurologic disorders accounting for the remaining one-third.
The vast majority of primary medical interventions are informed by and implemented upon population based studies. This is a problem since a single individual cannot be adequately represented by an entire population due to genetic and environmental heterogeneity within the population.
Few examples demonstrate how genomics might be proactively incorporated into new models for medical practice, and what infrastructure will be needed to support data generation and use. The methods described herein allow the integration of disparate orthogonal health data in a quantitative way to enable disease diagnosis and the determination of an optimal treatment plan. These methods are also useful for determining an increased risk of a future diagnosis of a disease, and importantly they allow for the identification of sub symptomatic diseases allowing earlier treatment and intervention in order to increase positive health outcomes.
Genomics as currently applied has been disappointing in its ability to unravel the “missing heritability” of most age-related chronic diseases, and other common diseases. This is rapidly changing as a result of public and private efforts to expand sequencing. First, we are increasingly finding and seeing supporting evidence for the increasing recognition of rare variants with large effect sizes. Combining this with advancements in monogenic and polygenic methodologies to assess causation including Mendelian randomization methods, extension of genome-wide association study to create hazard models, and continued exploration of pleiotropy, increase clinical utility. Second, increasingly detailed mapping of molecular pathways and mechanisms associated with diseases and risk factors provide a much needed improved capability to link genotype and phenotype data. Described herein, we demonstrate the use of global metabolomics in mapping to genomic defects. This can significantly strengthen with additional experience and automation. Thirdly, we quantitatively integrate genomics with other clinical data, particularly advanced imaging data, to create point-of-care clinical decision support. For example, if one queries more than 40,000 genomes (individuals and families), genotype-phenotype associations can be described with millisecond response times. The methods described herein prioritize individual opportunities for tertiary (disease treatment), secondary (risk factor control), and primary prevention using human- and machine-driven feature extraction.
The value of evolving medical practice from disease diagnosis to risk detection is supported by the study in Example 1. For example, we recommended follow-up imaging studies for slightly more than one-third of our study participants. Some of this is the nature of screening, which drives need for more definitive imaging studies better suited to specific abnormalities. Other instances of referral were intended to identify change over a specified time period which might be suggestive of cancer such as finding a cystic pancreatic lesion or instability of a vascular lesion such an intracranial aneurysm. In some instances, we don't know enough to confidently predict the natural course of these findings, and as a result may cause unnecessary anxiety and unneeded surgery. However, the life-threatening consequences and relatively high prevalence of diseases associated with these lesions suggests that early recognition is likely to be beneficial for most individuals. Expansion of some or all of our approach to broader populations requires the methods described herein.
The methods, computer media, and systems described herein deploy genome sequencing (e.g., whole genome sequencing, exosome sequencing, SNP typing) in combination with one or more other routine and advanced diagnostic technologies including: microbiome sequencing (e.g., gut or dermal microbiome); global metabolomics; 3D/4D imaging focusing on non-contrast whole-body magnetic resonance imaging and echocardiogram; 2-week cardiac monitoring; and functional neurologic testing to detect risk for age-related chronic diseases.

In addition to the phenotypic or clinical measurements gathered from an individual the health metric comprises nucleic acid sequence data from an individual. The nucleic acid sequence can comprise one or more DNA sequences. In certain embodiments, the DNA sequence comprises a sequence for an individual's whole genome. In certain embodiments, the DNA sequence comprises a sequence for only the high confidence regions of an individual's whole genome. For example the high confidence region of an individual's whole genome can be defined by the NA12878 Genome-In-A-Bottle call set (GiaB v2.19). In certain embodiments, the DNA sequence comprises a sequence for greater than 99%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, or 60% of the high confidence region of an individual's whole genome as defined by the GiaB v2.19.

In certain embodiments, DNA sequence data for use with the methods, systems and media, described herein, is generated by any suitable method. The DNA sequence data can be generated by Sanger sequencing or by any next-generation sequencing technology. In certain embodiments, the DNA sequence data is generated, by way of non-limiting example, by pyrosequencing, sequencing by synthesis, sequencing by ligation, ion semiconductor sequencing, or single molecule real time sequencing.

In certain embodiments, GSVs are determined by a third party and received by the party performing the method. In certain embodiments, determining a GSV encompasses receiving a list or file that comprises an individual's GSVs. The health metrics utilize a plurality of GSVs. In some cases greater than 10; 50; 100; 500; 1,000; 10,000; 100,000; or 1,000,000 GSVs, including increments therein when compared to a reference sequence, are utilized for the health metric.
The genomic sequence variants of an individual are used to set that individual's genetic risk. This genetic risk is defined by a genetic risk rule. This genetic risk can be disease specific, for example, diabetes, heart failure, specific cancers, or other mortalities. GSVs are first determined and then their potential pathogenicity is determined. Pathogenicity can be determined by using for example a statistical association of the GSV with a given disease or a given gene involved in a given disease. The pathogenicity can be defined based upon a score such as a CADD score, presence in the NCBI ClinVar database, or by other methods of determining a selection pressure on the specific genomic locus. Methods for defining selective pressure through for example a context dependent tolerability score, an n-variant score, regional variation score or a protein tolerability score can be implemented such as those described in U.S. Provisional Application Ser. No. 62/333,653 or U.S. Provisional Application Ser. No. 62/410,783 and are incorporated by reference herein in their entirety. The genetic risk rule can for example rank pathogenic variants by percentile, quartile, quintile, etc. For example, only the top 99th, 98th, 97th, 96th, 95th, 94th, 93th, 92nd, 91st, 90th, 80th, 70th, 60th, or 50th percentile, including increments therein, may be used when determining a genetic risk.
Referring to
Health Metrics
The methods, computer media, and systems described herein utilize a plurality of health metrics to diagnose diseases and risk factors. The method can deploy 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, or more independent health metrics, including increments therein. A health metric is a discreet result from a diagnostic test determined by a physician, laboratory, specialist, or questionnaire. The health metrics of this disclosure comprise phenotypic or clinical measurements gathered from an individual. The health measurement can be those normally acquired in a physician's office such as height, weight, blood pressure, reflex measurements, skin fold measurements, temperature, blood oxygen saturation, resting pulse rate, urinalysis and the like. The health measurement can be those normally measured by a laboratory using a patient's blood, plasma, serum, saliva, stool, urine, semen, or pap smear and can include: analysis of blood lipids, such as, fatty acids, non-esterified fatty acids, omega-3 fatty acids, cholesterols, high-density lipoprotein (HDL), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), chylomicrons, triglycerides, diglycerides, monoglycerides; measures of carbohydrate usage, such as glucose levels (fasting or non-fasting), oral glucose tolerance test, h1Ac; liver enzymes and markers, such as, aspartate aminotransferase, alkaline phosphatase, aspartate aminotransferase, albumin, bilirubin; electrolytes, such as, calcium, sodium, potassium, magnesium, chloride; blood pH, bicarbonate, hemoglobin, red cell count, white blood cell count; specific markers for cancer such as, for example, prostate specific antigen; tests for viral infection such as antibodies against or sequences from, HIV, hepatitis A, B, or C; or bacterial or yeast cultures. The health measurement can be more specialized and comprise histological examination, MM analysis, EKG analysis, EEG analysis, cardiac stress test, psychological evaluation, gait and balance test, ultrasound, CAT scan, X-rays, bone density measurements, body composition measurements, colonoscopy, or PET scans. The health measurement can comprise demographic factors such as age, gender, race, genetic origin or ancestry, health history, or family history. The health measurement can also comprise measurements that are tracked by wearable devices, such as a wearable health monitor, including activity, sleep/wake cycle, sleep analysis, pulse rate and rhythm and the like.
The measured health metrics of an individual are used to set that individual's non-genetic risk. This non-genetic risk can be disease specific, for example, diabetes, heart failure, specific cancers, or other mortalities. This non-genetic risk is defined by a non-genetic risk rule. Physiological measurements are ranked and segmented by known distributions of the physiological measurement. For example, LDL in the 75th percentile or above may be used when determining a risk for a congestive heart failure. The non-genetic risk rule can rank physiological measurements by percentile, quartile, quintile, etc. For example, only the top 99th, 98th, 97th, 96th, 95th, 94th, 93rd, 92nd, 91st, 90th, 80th, 80th, 70th, 60th, or 50th percentile, including increments therein, may be used when determining a non-genetic risk. The non-genetic risk can also be defined in part by a binary response such as a Yes or NO on a questionnaire concerning health history, environmental factors, or family history, or by a plus or minus result from for example an MM or EKG test.
The methods described herein for determining risk for and diagnose of medical conditions comprise combining a plurality of health metrics wherein one of the health metrics comprise nucleotide sequence data and at least one other health metric, but can comprise 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, or more independent health metrics, including increments therein. The genetic and non-genetic risk rules are then combined and appropriately weighted per disease. For example the genetic risk can be assigned a weight that is 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100% more, including increments therein, than the non-genetic risk. For example the non-genetic risk can be assigned a weight that is 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100% more, including increments therein, than the genetic risk. For example, the genetic risk can be assigned a weight that is 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 7-fold, 8-fold, 9-fold, 10-fold, 20-fold, 50-fold, or 100-fold more, including increments therein, than the non-genetic risk. For example, the non-genetic risk can be assigned a weight that is 2-fold, 3-fold, 4-fold, 5-fold, 6-fold, 7-fold, 8-fold, 9-fold, 10-fold, 20-fold, 50-fold, or 100-fold more, including increments therein, than the genetic risk.

Integrating Genotype and Phenotype Information Uncovers Undiagnosed Conditions and Risk Factors
We enrolled 209 study participants, median age 55 yrs., range 20-98 yrs., 34.5% female, between September 10, 2015 and May 16, 2016. Twenty-one (10%) of the 209 participants were from 7 families. Selected characteristics comparing study participants to age and gender-adjusted NHANES cohort, a US population-based sample, is shown in Table 1. Routine clinical laboratory testing was obtained on 90 study participants (43%); Quantose IR (including fasting blood glucose) was obtained on 208 participants and included fasting blood glucose. Magnetic resonance imaging-based quantitative body compartment-specific fat and muscle estimation was conducted on 126 participants (60%). Some portion of the intended 2-week cardiac rhythm monitoring was completed on 140 (67%) participants; the median duration of monitoring was 5.9 days (range 0.8-14 days) (
We identified seventeen study participants (8%) with evidence of age-related chronic diseases considered significant and highly actionable requiring prompt medical attention following confirmation of screening findings: four early stage neoplasias (thymoma, renal cell carcinoma, and two high grade prostate neoplasms), one enlarged aortic root, two newly recognized atrial fibrillation cases, two medically significant arrhythmias, one 3rd degree heart block, one primary biliary cholangitis, and one xanthinuria (see Table 2). Some individuals had no detectable genetic risk emphasizing the value of phenotyping technology.
Table 3 lists the pathogenic associations of genomic variants. 52 (25%, 1:4) participants had likely mechanistic genotype-phenotype associations (
We identified 164 (78%, >3:4) participants with evidence of age-related chronic disease or risk factors. One-hundred-and-eighteen study participants (56%) had evidence of diabetes or risk for diabetes: 15 (7%) had type 2 diabetes; 80 (38%) had pre-diabetes (38%), and 23 (11%) had insulin resistance (based on Quantose IR). Only 19 (16%) reported a history of type 2 diabetes or pre- diabetes (Table 1). One-hundred-and-twenty-four participants (59%) had evidence of atherosclerotic disease or risk. Thirty-three (16%) had evidence of metabolic syndrome. Twenty-eight participants (13%) met a screening definition for non-alcoholic fatty liver disease (NAFLD), and one had suspected non-alcoholic steatohepatitis (NASH). Many participants had multiple over-lapping conditions including: 29 with pre-diabetes and atherosclerotic disease or risk; 19 with pre-diabetes, atherosclerotic disease or risk, and metabolic syndrome and; 13 with insulin resistance and atherosclerotic disease or risk (
We identified 10 unique alleles in 14 subjects with metabolic signatures consistent with penetrance. Metabolic pathways impacted by the allelic differences included fatty acid beta oxidation, fatty acid synthesis, urea cycle, and signatures associated with oxidative stress. Strong metabolic signatures were observed for two polymorphisms matching the genes' function. Two heterozygous ACADS variants, c.1510G>A and c.1030C>T, coding for the short-chain acyl- Coenzyme A dehydrogenase (SCAD) were detected in one case. In another case, the heterozygous ACADM variant c.1456C>T coding for medium-chain acyl-Coenzyme A dehydrogenase (MCAD) was detected and interestingly both enzymes participate in fatty acid beta-oxidation by reducing different fatty acid chain length. SCAD specifically acts on the short chain fatty acid butyryl-CoA and MCAD reduces acyl-CoA chains containing 6-12 carbons. In the absence of SCAD activity, byproducts of butyryl-CoA including butyrycarnitine and ethylmalonate accumulate. Greatly elevated levels of butyrylcarnitine and ethylmalonate (Z-scores above 97.5th percentile) were observed in the plasma suggestive of combined metabolic penetrance of these variants. Moreover, greatly elevated medium chain acyl-carnitines, hexanoylcarnitine, octanoylcarnitine and decanoylcarnitine (Z-scores above 97.5th percentile) were detected suggestive of reduced MCAD activity. Large genome-wide association studies combined with metabolic profiling have previously identified associations between ACADS and MCAD and their respective metabolic substrates lending support to the metabolic penetrance observed on an individual basis in this study. We previously reported on additional metabolomic/genetic variants which are heterozygotes for known recessively inherited disorders. These studies established that “carrier” disease state does not reflect carrier for individual metabolic variation. The number of adult cases of metabolic penetrance will continue to expand using this approach.
Metabolomics analysis also detected xanthinuria in an individual with early onset (20's) recurrent renal stones (6 episodes) as well as the drug effect of xanthine oxidase inhibitors in 3 other individuals. Although hypoxanthine and especially xanthine levels were elevated in both cases, normal urate and elevated orotate and orotidine levels, due to perturbed pyrimidine synthesis , were only observed in individuals taking xanthine oxidase inhibitors (allopurinols) for their gout conditions.
We enrolled active adults >18 years old (without acute illness, activity-limiting unexplained illness or symptoms, or known active cancer) able to come for 6-8 hours of on-site data collection, were able to undergo magnetic resonance imaging without sedation, in the case of women were not pregnant or attempting to become pregnant, and were interested in undergoing a novel precision medicine screening approach for disease risk detection including genomics and other testing, as part of an institutional review board-approved clinical research protocol. Study results were returned to study participants who were encouraged to involve their primary care physicians.
Participants underwent a verbal review of the institutional review board-approved consent (Western Institutional Review Board) and were given time to ask and receive answers to questions during a one-half to one-hour sessions conducted by health professionals. Study participants underwent standardized activities related to data collection and return of results in pre-visit, visit, and post-visit phases during a 1-year study period.
Selected data were collected regarding past medical and family history, risk factors, and medical symptoms prior to or during study participant visit. Participants were instructed to stop taking supplements for 72 hours, and to fast after dinner the night before their morning appointment. On the day of visit, blood was obtained for whole genome sequencing (Human Longevity, Inc.), global metabolomics and QUANTOSE™ IR (Metabolon), and routine clinical laboratory tests (LabCorp Inc.™) Two-week cardiac rhythm monitoring (Zio XT Patch™, iRhythm Technologies, Inc.™) kits were provided with instructions for use, or monitoring was initiated during visit. Height, weight, and sitting blood pressure were obtained. Genomic variants were annotated using integrated public and proprietary annotation sources in the HLI Knowledgebase including ClinVar, and HGMD (Qiagen). Monogenic rare variants were classified as pathogenic (P), likely pathogenic (LP), or variant of uncertain significance (VUS). The HLI Knowledgebase integrates allele frequencies for variants derived from HU's database of >12,000 sequences and provides a platform for query of these variants with annotation data.
To identify potentially medically significant rare monogenic variants we used an internal version (release 0.27) of HLI Search™ in a two-step process: the first step focused on allele frequency <1% in the HLI cohort with annotation using ClinVar and HGMD as well as predicted loss of function variants; the second step focused on participant-specific phenotype-driven queries using an allele frequency of <1% based on family and individual medical history as well as abnormal clinical testing results. Global metabolic profiling was performed using ultrahigh performance liquid- phase chromatography separation coupled with tandem mass spectrometry to assess the metabolic penetrance of the variants in these subject. Z-scores were calculated for all metabolites in each subject against a reference cohort consisting of 42 fasted subjects of normal health, and metabolites with Z-scores below the 2.5th or above the 97.5th percentiles of the reference cohort were considered to be potentially indicative of metabolic abnormalities that warranted further investigation. Integration of metabolomic and gene sequence data was achieved by a proprietary pathway analysis program developed by Metabolon and HLI.
Study participants underwent whole body magnetic resonance imaging (GE Discovery MR750w 3.0T) in research mode using protocols and post-processing for volumetric brain imaging (Neuroquant™, CorTechs Laboratories™), cancer detection (using restriction spectrum imaging), neurovascular and cardiovascular visualization, liver-specific fat and iron estimation, and quantitative body compartment-specific fat and muscle estimation (AMRA); other post-processing was done by MMIS. GE Lunar iDXA with Pro Package was used for skeletal and metabolic health assessment. Magnetic resonance imaging and iDXA. GE Vivid E95 was used for echocardiography and a GE Mac 2000 was used to obtain a 12-lead resting electrocardiogram. Two-week cardiac monitoring, electrocardiogram, and echocardiography were interpreted by a physician. Participants with likely mechanistic genomic findings correlating with clinical data were identified by expert review to identify convergent genomic and clinical (or phenotype) data relationships including at least two clinical (or phenotype) data elements supporting a genomic observation, including three generation family history and metabolite level correlation based on pathway mapping. Baseline characteristics including reported past medical history for major categories of age-related chronic diseases by study participants were compared to responses from NHANES, a US population-based cohort (Table 1), adjusted for age and sex distributions. Study participants with evidence of age-related chronic diseases considered significant and highly actionable were defined as new genomic and/or other clinical findings which based on current medical practice indicated the need for medical attention to avoid potentially life-threatening consequences immediately or within 30 days from their visit. Participants with evidence of age-related chronic disease or disease risk factors were identified as including: 1) type 2 diabetes, pre-diabetes and insulin resistance (Quantose IR); 2) likely atherosclerotic disease or risk; 3) metabolic syndrome ; 4) non-alcoholic fatty liver disease and non- alcoholic steatohepatitis, based on clinical guidelines or other recent literature. Measured fasting blood glucose, hemoglobin A1C, personal medical history for diabetes, or Quantose IR was used to identify participants as having diabetes, pre-diabetes or insulin resistance. The presence of any of the following were considered to be evidence of likely atherosclerotic disease or risk: “yes” in response to any of the following questions: 1) Ever told you had coronary artery disease, 2) Ever told you had a heart attack, 3) Ever told you had congestive heart failure, 4) Taking prescription for hypertension, and 5) Taking prescription for cholesterol, or if sitting blood pressure >normal, LDL cholesterol>normal, or Lipoprotein-associated phospholipase A2 (Lp-PLA2)>normal. The presence of any three of the following 5 criteria were considered to be evidence of metabolic syndrome: 1) visceral adipose tissue measured by MM (post-processing by AMRA™)>2SD above normal, or android/gynoid fat measured by iDXA >normal; 2) triglycerides>150 mg/dL; 3) HDL cholesterol<40 mg/dL in men and <50 mg/dL in women or the participant is currently taking prescribed medicine for high cholesterol; 4) blood pressure>130/85 mmHg or the participant is currently taking prescription for hypertension; 5) Measured fasting glucose or hemoglobin A1c indicates pre-diabetes or “borderline” in response to the question - Doctor told you have diabetes. The presence of non-alcoholic fatty liver disease or nonalcoholic steatohepatitis were considered likely if: for non-alcoholic fatty liver disease MM-based estimate liver fat was <4% and did not have alcohol dependence, and for these individuals we used a formula including other demographic and laboratory data to identify likely non-alcoholic steatohepatitis.
