Using population-based female twins, Kendler37 tested a multiple-threshold model in which melancholia exists as a more severe form on the same continuum of liability as nonmelancholic MDD. BACKGROUND: Major depressive disorder (MDD) is the second largest cause of global disease burden. An important theoretical question is the expected pattern of findings if we selected a more homogeneous and more severely ill cohort. Using two different recently proposed methods designed to estimate the heritability of a phenotype that is attributable to genome-wide SNPs, we show that SNPs on current platforms contain substantial information concerning the additive …  P, Zhu  K, Using LDAK, we generated SNP weights that reflect a correlation with surrounding markers to construct GRMs adjusted for local linkage disequilibrium. The dark and light blue areas display 50% and 95% CIs, respectively, obtained by bootstrapping SNP sets.  BM, Background: Major Depressive Disorder (MDD) is the second largest cause of global disease burden. First, it is possible that DHSs are enriched in tissues other than brain tissue given that we have prior evidence of the role of genes with mitochondrial function in MDD,5 metabolism is regulated in many tissues, and many regulatory mechanisms are common to many tissues. Research is needed to quantify the relative contribution of classes of genetic variation across the genome to inform future genetic studies of MDD. Dr Peterson is supported by NIH T32 grant MH020030.  Z, The link is strong enough that some with depression have …  NL. Purcell We determined 95% CIs for enrichment curves by bootstrapping and assessed significance by empirical null distributions (eAppendix in the Supplement). Although these estimates were similar to those reported for populations of European descent (approximately 21%)10 but lower than the 37% reported by previous twin studies,3 heritability is a population-specific measure.  D, Hemani Burden of depressive disorders by country, sex, age, and year: findings from the global burden of disease study 2010. Sometimes the mood switches are dramatic and rapid, but most often they are gradual. It has an estimated heritability of 37%, but published genome-wide association studies have so far identified few risk loci. Could the estimates of heritability of MD be biased by the well-demonstrated genetic influences on memory? © 2021 American Medical Association. Main Outcome(s) and Measure(s) Antidepressant response measured as Remission and Percentage Improvement. It has an estimated heritability of 37%, but published genome-wide association studies have so far identified few risk loci. Genetic heterogeneity in human disease.  ET, Goldstein  MT, Humbert Gusev  MC, Kendler Findings  Meaning  Permutations were performed to verify that P values were not inflated (eAppendix in the Supplement). The Table shows a significant (odds ratio [OR], 1.011; 95% CI, 1.003-1.018; P = .004) excess of singleton deleterious mutations in brain-expressed genes in cases. That is the case for major depression.  NR, Stone High ... Higher levels of Major Depressive Disorder are associated with _____. Dr Bacanu is supported by NIH grants R21MH100560 and R21AA022717. Mitochondrial DNA polymerase-γ and human disease. It has an estimated heritability of 37%, but published genome-wide association studies have so far identified few risk loci. We constructed polygenic risk scores within CONVERGE by 2 methods. Cases were recurrent and quite severe, with approximately 85% meeting the criteria for melancholia. The epidemiology of depression across cultures. Sullivan  K, Li Major depressive disorder is defined as marked and persistent depressed mood associated with physical and cognitive signs and symptoms. To determine the statistical significance of any particular enrichment curve (ie, how unlikely under the null hypothesis of no enrichment), we assessed the statistical significance of enrichment on the intervals between –log10(p), between 5 and 6, and separately upward of 6 by binomial tests, and then we combined these P values by the Fisher exact method. Anxiety and sequential comorbidity of anxiety disorders and MDD revealed h2of 49% and 53%, respectively, and strong positive genetic correlation (rhog = 0.92, P = 7.3 × 10−7). Enrichment of variant associations was seen in protein-coding regions, 3′ UTR, and DNase I-hypersensitive sites, as was significant burden of singleton exonic variants in MDD, particularly in genes expressed in the brain or with mitochondrial gene products. True Positive Rates in the Exomes of Variant Calls Occurring Only Once in the CONVERGE Cohort, eTable 6. Second, our results support a substantial polygenic component to the risk of MDD involving many alleles of individually very small effect. Studies of families in which major depressive disorder occurs strongly suggest that a genetic component may be a key factor in the development of the disorder.  JE, You might have a parent, sibling, or child with depression but not develop it yourself. JAMA Psychiatry. Strategies to dissect phenotypic and genetic heterogeneity of major depressive disorder (MDD) have mainly relied on subphenotypes, such as age at onset (AAO) and recurrence/episodicity. Partitioning heritability by minor allele frequency indicated that the variance explained was distributed across the allelic frequency spectrum, although relatively common SNPs accounted for a disproportionate fraction of risk. doi:10.1001/jamapsychiatry.2016.3578. The interview assessed a history of depressive onsets and recoveries in the last year to the nearest month. Genome-wide polygenic risk scores constructed from SNPs were significantly associated with MDD liability, accounting for 1.1% of the variance in risk compared with 0.6% estimated by a similar method for European samples.23 Significant heritability was found across all chromosomes, with the amount of variance explained proportional to length, further demonstrating an underlying polygenic architecture of MDD. Genetic variance estimation with imputed variants finds negligible missing heritability for human height and body mass index. SIRT1 mediates depression-like behaviors in the nucleus accumbens. A significant enrichment in deleterious variants in nuclear-encoded mitochondrial genes (OR, 1.075; 95% CI, 1.018-1.135; P = .009) was found.  JL, Fromer  G, Johnson Data were collected from August 1, 2008, to October 31, 2012.  Y, Kaluzova  CM,  J, Lee  et al; LifeLines Cohort Study.  J, Kendler A mega-analysis of genome-wide association studies for major depressive disorder.  ME, Shadick Enrichment of SNPs associated with DNase I-hypersensitive sites was also found in many tissue types, including brain tissue. Major depressive disorder (also known as ... accounting for the high heritability and prevalence of depression by proposing that certain components of depression are adaptations, [72] such as the behaviors relating to attachment and social rank.  et al. In contrast, no significant enrichment was seen for associations between MDD and variants in genes not expressed in the brain (OR, 1.000; 95% CI, 0.994-1.014; P = .41).  B, Todd-Brown the narrow sense heritability of MDD to be 37%, confirming the involvement of genetic factors in MDD (2).  N, Price What is the genetic architecture of recurrent major depressive disorder (MDD) in Han Chinese women? Rory most likely has: Persistent depressive disorder. USA.gov. Author Contributions: Drs Kendler and Flint had full access to all the data and take responsibility for the integrity of the data and the accuracy of the data analysis. Specifically, SNPs in genic regions, especially those in introns and 3′ UTR, explain more variance than in noncoding regions. The CONVERGE (China, Oxford, and Virginia Commonwealth University Experimental Research on Genetic Epidemiology) study collected data on 5278 patients with recurrent MDD from 58 provincial mental health centers and psychiatric departments of general medical hospitals in 45 cities and 23 provinces of China.  G, 2017;74(2):162–168. HHS  L, Fenik  ME, Visscher The NAD+-dependent deacetylase SIRT1 modulates CLOCK-mediated chromatin remodeling and circadian control. To assess the relative contribution of heritability of SNPs in functional categories, we partitioned SNPs into functional annotations (eg, exon, intron, or 3′ UTR) using ANNOVAR, version 2015 (QIAGEN Bioinformatics).18 The functional classes were fitted jointly in a single GREML model.

In the general population, the rate of occurrence of the major depressive disorder appears to be relatively consistent in all cultures around the world, with the rate of occurrence falling somewhere between 8% and 12%. Because these tests explore whether the 2 ORs are significantly different, we applied a Bonferroni corrected threshold of 0.025 (0.05/2).  et al. Genome-wide association studies (GWAS) have identified risk variants for many psychiatric disorders, but until recently, no replicated genome-wide significant loci had been identified for MDD, as clinically defined by the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision).4,5 This lack of genome-wide significant loci may reflect the etiological heterogeneity of MDD, especially given the evidence that the genetic liability to MDD is only partially shared between the sexes.6,7 The CONVERGE (China, Oxford, and Virginia Commonwealth University Experimental Research on Genetic Epidemiology) study of MDD was designed to reduce phenotypic and genetic heterogeneity by examining only severe cases and carefully screened control patients, all of whom were female and of Han Chinese ancestry.  M, Hakonarson Participants Diagnosed with Major Depressive Disorder and assessed for depressive symptoms before and after prescription of an antidepressant medication. Uher While SNP-based heritability estimates for melancholic and nonmelancholic MDD were not significantly different (eTable 6 in the Supplement), polygenic risk scores were more predictive of melancholic rather than nonmelancholic MDD (P = .002) (eTable 7 in the Supplement). Despite the moderate, well-demonstrated heritability of major depressive disorder (MDD), there has been limited success in identifying replicable genetic risk loci, suggesting a complex genetic architecture. Terms of Use|  RM, Weinblatt 1999 Apr;56(4):322-7. doi: 10.1001/archpsyc.56.4.322. Data for the whole sample were best explained by an additive genetic model, with heritability of depressive symptom scores estimated at 79%. Heritability is probably 40-50%, and might be higher for severe depression. Design elements of CONVERGE sought to reduce genetic and phenotypic heterogeneity. He also suffers from poor appetite and low self-esteem. Strategies to dissect phenotypic and genetic heterogeneity of major depressive disorder (MDD) have mainly relied on subphenotypes, such as age at onset (AAO) and recurrence/episodicity.  HD, Hesterman We are guided by the only empirical study we know regarding this question.  D.  Principal components analysis corrects for stratification in genome-wide association studies. Enrichment of SNPs With Small P Values in MD Analysis for DHS in ENCODE Samples, eFigure 4. Genome-wide Complex Trait Analysis estimates of SNP h2 for major depressive disorder partitioned by minor allele frequency quintile. Results  Purcell  et al; Major Depressive Disorder Working Group of the Psychiatric GWAS Consortium. Results confirm a complex genetic architecture for MDD, supporting etiological mechanisms for both common and rare genetic variation to MDD risk. Results support a complex etiology for MDD and highlight the value of analyzing components of heritability to clarify genetic architecture. We then applied a permutation-based method to investigate whether the ORs were significantly different from the average gene genome-wide value. An alternative approach using LDAK, which accounts for local linkage disequilibrium by weighting all SNPs on the basis of correlations with surrounding SNPs, estimated heritability at 29.4% (SE = 4.6%; P = 9.09 × 10−11). 2002 Jul;32(5):829-42. doi: 10.1017/s0033291702005858.  et al.  KS. Williams  G, Gusev Single-nucleotide polymorphism-based heritability estimates were obtained using Genome-wide Complex Trait Analysis (GCTA), version 1.24.7,9 and Linkage Disequilibrium Adjusted Kinship (LDAK), version 5.9.17 Genetic relatedness matrices (GRMs) were constructed from 4.7M hard called SNPs that passed several quality control parameters: genotype probability (Pr[G]) of 0.9 or more, less than 1% missing rate, MAF of 0.005 or more, and Hardy-Weinberg equilibrium P > 10−6. Variance in Major Depressive Disorder Risk Explained by Single-Nucleotide Polymorphisms (SNP) of Varying Minor Allele Frequency, Figure 2. A Swedish national twin study of lifetime major depression. To estimate the contribution of each chromosome to the total heritability as well as to test for inflation due to cryptic relatedness, we constructed GRMs for each chromosome and estimated per-chromosome heritability using each GRM separately and all GRMs jointly. Okbay Our website uses cookies to enhance your experience. The Genetic Architecture of Major Depressive Disorder in Han Chinese Women, eTable 1. The probability of an enrichment curve at least this high under random permutations of DNase status of SNPs is less than 0.001. eFigure 3 in the Supplement shows enrichment of DHS in all of the samples available in July 2014 from the Encyclopedia of DNA Elements. Results Genome-wide analysis of Remission ( Nremit =1,852, Nnon-remit =3,299) and Percentage … Wang In this case-control study of MDD, aggregate genetic risk accounted for 21.4% of the variance in MDD liability with significant heritability found across chromosomes and the allelic spectrum. B, Adjusted (per SNP [single-nucleotide polymorphism]) GCTA estimates of SNP h2 partitioned by expected functional category. Depression is common and costly, and it is projected to be the second leading cause of disability worldwide by 2020 (7–10). Drs Flint and Kendler are joint senior authors.  S, Neale Regional heritability Major depressive disorder (MDD) contributes 8.2% of the global burden of disease (1).  A, Kuper Bipolar disorder has a _____ rate of heritability suggesting a biological cause. 2001 Apr;10(2):375-90. A similar pattern was found if heritability was assessed for the number of interviews in which criteria for MD were met. Using genomic annotation databases, such as the Encyclopedia of DNA Elements, the enrichment of variants in regulatory elements and protein-coding regions can be assessed.12,13 Given our whole-genome sequencing data, enrichment of rare deleterious variants can also be tested. Personality and major depression: a Swedish longitudinal, population-based twin study. Objective: Although family, twin and adoption studies have suggested that lifetime major depression (MD) is a heritable condition, nearly all these studies have relied for the diagnosis on long-term human memory, which is fallible and potentially biased. It has been suggested that common variants have a smaller role in the etiology of MDD than originally posited by the common-disease–common-variant hypothesis because of the low proportion of variance explained by earlier GWAS.24,25 However, we found that the bulk of detectable heritability comes from common variants (MAF>0.19, the 2 topmost quintiles).  CO, Neale  DB. Major depressive disorder is partially genetic. To assess the relative contribution of MAF to heritability estimates, we partitioned SNPs into MAF quintiles. To address population stratification, we constructed 10 ancestry principal components (PC) using EIGENSOFT 3.0 and smartpca (Harvard University).15,16 To circumvent overfitting, we used only PC1 and PC2, which distinguished north-south regional differences (eFigure 1 in the Supplement).  M,  DJ. PC1 and PC2 were included as covariates. Results: Major depressive disorder Christian Otte 1 , Stefan M. Gold 1,2 , Brenda W. Penninx 3 , Carmine M. Pariante 4 , Amit Etkin 5 , Maurizio Fava 6 , David C. Mohr 7 and Alan F. Schatzberg 5 To assess the contribution of heritability due to SNPs in coding vs noncoding regions, we partitioned SNPs into their proposed genic annotations. Screened controls (n = 5196) were recruited from a range of locations, including general hospitals and local community centers. The empirical P value was .04 for the OR observed in the brain-expressed gene set and was .02 for that in the nuclear-encoded mitochondrial genes (eFigure 7 in the Supplement). Cai  M, Gardner Cirulli The variance in MDD explained by each chromosome was proportional to its length (r = 0.680; r2 = 0.463; P = .0003). All Rights Reserved. Enrichment curve for “FrontalCortexOC” is a Loess curve interpolating the ratio of the number of single-nucleotide polymorphism (SNPs) whose association P value is smaller than various thresholds (x-axis) to the proportion of P values from all measured SNPs in DNase I-hypersensitive sites smaller than the same thresholds.  SH, Ripke The aims of this study are to investigate the familiality of AAO and episode frequency in MDD and to assess the proportion of their variance … Variance of MD Explained (h2) by Each Chromosome as a Function of Its Length, eFigure 2b. sign up for alerts, and more, to access your subscriptions, sign up for alerts, and more, to download free article PDFs, sign up for alerts, customize your interests, and more, to make a comment, download free article PDFs, sign up for alerts and more, Archives of Neurology & Psychiatry (1919-1959), FDA Approval and Regulation of Pharmaceuticals, 1983-2018, Global Burden of Skin Diseases, 1990-2017, Health Care Spending in the US and Other High-Income Countries, Life Expectancy and Mortality Rates in the United States, 1959-2017, Medical Marketing in the United States, 1997-2016, Practices to Foster Physician Presence and Connection With Patients in the Clinical Encounter, US Burden of Cardiovascular Disease, 1990-2016, US Burden of Neurological Disease, 1990-2017, Waste in the US Health Care System: Estimated Costs and Potential for Savings, Register for email alerts with links to free full-text articles.

Kendler KS, Gatz M, Gardner CO, Pedersen NL. PLINK: a tool set for whole-genome association and population-based linkage analyses. We used low-coverage sequence data to test whether MDD cases have a polygenic burden of rare deleterious coding variants.  Y, Zhan Sparse whole-genome sequencing identifies two loci for major depressive disorder. Controls were recruited from several locations, including general hospitals and local community centers. The heritability estimate for mania based on this model was 0.85 (95% CI, 0.74-0.93) and that for depression was 0.72 (95% CI, 0.6-0.81).  R.  The role of genetic variation in the causation of mental illness: an evolution-informed framework.  et al. Conclusion: Research is needed to quantify the relative contribution of classes of genetic variation across the genome to inform future genetic studies of MDD. For example, SIRT1 (OMIM 604479) influences processes that feature among the vegetative symptoms32 of MDD: alterations in food intake,33 wakefulness,34 and circadian rhythms.35 The involvement of mitochondrial genes might also explain why MDD increases the risk of cardiovascular disease.36. 2006 Oct;63(10):1113-20. doi: 10.1001/archpsyc.63.10.1113. It has an estimated heritability of 37% but published genome-wide association studies have so … Accessibility Statement, Figure 1. Using these linkage disequilibrium–independent SNPs, we computed per-individual polygenic scores on the basis of varying P value threshold signifying the proportion of SNPs with smaller P values in the training set; P value thresholds ranged from 0.001 to 1.8 Second, using the sample 1–sample 2 split, we also estimated SNP effects by the best linear unbiased prediction (BLUP) method implemented in GCTA.9 The latter scores were constructed with the profile option in PLINK,20 using SNP BLUP solutions as weights. Second, regulatory elements in brain cells are harder to identify by DHS because of greater cell-type heterogeneity than is found in most somatic tissues. Yet, evidence on whether these subphenotypes are familial or heritable is scarce. Finucane  WK, Rasgon We attained the greatest predictive power using BLUP solutions (eTable 4 in the Supplement); this score was associated with MDD (P < 4.6 × 10−5), accounting for 1.1% of the variability in MDD risk. Our results apply to Han Chinese women, aged between 30 and 60 years, with recurrent depression. CONVERGE Consortium. The study protocol was approved by the Ethical Review Board of Oxford University and the ethics committees of all participating hospitals in China.  S, Wray Our dense set of markers, which captures significantly more common and rare variation than is present on genotyping arrays, allows for a unique opportunity to add insight into the genetic architecture of this common and debilitating psychiatric disorder.
