This finding contrasts with the finding of a similar analysis carried out on a large schizophrenia cohort, in which heritability was distributed more evenly across the quintiles.26 The excess of heritability attributable to the most common MAFs is, in part, possibly because the small reduction in reproductive fitness associated with mood disorders exerts little selective power to drive risk variants to lower allele frequency.27,28. It has an estimated heritability of 37%, but published genome-wide association studies have so far identified few risk loci. Based on these findings, we predict that the heritability of MDD in CONVERGE would not differ substantially from other samples, but the CONVERGE sample, in general, and our melancholic cases, on average, would have higher genetic liability.  KE, Marsh  et al. High ... Higher levels of Major Depressive Disorder are associated with _____. © 2021 American Medical Association. Ferrari We find enrichment of SNPs with low P values associated with MDD in DHS of many cell types, including brain-related tissues. A mega-analysis of genome-wide association studies for major depressive disorder.  CO, Pedersen 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. Genetic influences on human recall do not appear to contribute substantially to estimated heritability of MD. A significant proportion of variance was due to common variants, although rare variation also appears to contribute to MDD disease liability. A polygenic burden of rare disruptive mutations in schizophrenia. Results:  A, Baselmans Or it could mean that in some cases, the tendency to become depressed is almost completely genetic, and in other cases it is not … To assess the contribution of heritability due to SNPs in coding vs noncoding regions, we partitioned SNPs into their proposed genic annotations. All participants provided written informed consent. Could the estimates of heritability of MD be biased by the well-demonstrated genetic influences on memory?  SH, Trynka B, Adjusted (per SNP [single-nucleotide polymorphism]) GCTA estimates of SNP h2 partitioned by expected functional category.  N, Price Kendler Variance of MD Explained (h2) by Each Chromosome as a Function of Number of SNPs, eFigure 3. Cai  SM, Moran  |  Genetic risk for liability to recurrent MDD was partitioned using sparse whole-genome sequencing. 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. 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. Estimation of SNP-Based Heritability of MDD, Enrichment of DNase I-Hypersensitive Sites, Rare Variant Annotation and Enrichment Analysis, Cumulative Burden of Private Deleterious Exonic Variants.  MC. 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). Data were collected from August 1, 2008, to October 31, 2012. 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. Results support a complex etiology for MDD and highlight the value of analyzing components of heritability to clarify genetic architecture. Partitioning by genic annotation indicated a greater contribution of SNPs in protein-coding regions and within 3′-UTR regions of genes. Design elements of CONVERGE sought to reduce genetic and phenotypic heterogeneity.  CA. GWA studies of Major Depressive Disorder (MDD) in particular have so far been unsuccessful in detecting genome-wide significant SNPs. Variance in Major Depressive Disorder Risk Explained by Single-Nucleotide Polymorphisms (SNP) of Varying Minor Allele Frequency, Figure 2.  KS. Statistical analysis: Peterson, Cai, Bigdeli, Li, Reimers, Nikulova, Webb, Bacanu, Flint. Contrasting genetic architectures of schizophrenia and other complex diseases using fast variance-components analysis.  B, Gusev Using approximately 4.7M autosomal and X chromosome SNPs, we estimated that 21.4% of the variance in MDD risk (95% CI, 15.5-27.3; P < 1.0 × 10−16) is captured by genome-wide common variants (n = 10 474). Single-nucleotide polymorphisms with P values under 10−5 associated with MDD are 5 times as likely to lie in a DHS in this brain sample from the frontal cortex as are SNPs taken at random. Would you like email updates of new search results? A significant enrichment in deleterious variants in nuclear-encoded mitochondrial genes (OR, 1.075; 95% CI, 1.018-1.135; P = .009) was found. 2009 Sep;117(1-2):30-41. doi: 10.1016/j.jad.2008.12.004.  H.  Depression as an aetiologic and prognostic factor in coronary heart disease: a meta-analysis of 6362 events among 146 538 participants in 54 observational studies.  KS, Gatz When applying the P value threshold method, we attained the greatest predictive ability using P(t)<0.4; this score was associated with MDD (P < 3.0 × 10−6), accounting for 0.55% of variability in MDD liability (eTable 3 in the Supplement). Exon coordinates contained 96 130 824 base pair positions in 254 986 exons in 21 946 genes. Details appear in the eAppendix in the Supplement. Hudson  B, Todd-Brown  WK, Rasgon A user’s guide to the Encyclopedia of DNA Elements (ENCODE). PLINK: a tool set for whole-genome association and population-based linkage analyses. And many, like Merkin, who have struggled with major depressive disorder, worry they will pass the condition on to their children, especially as new neurobiological evidence into the disease’s underpinnings emerge. eTable 1 in the Supplement shows heritability estimates based on varying MDD prevalence, which increases with higher prevalence rates. A, Aggregate Genome-wide Complex Trait Analysis (GCTA) estimates. Major depressive disorder (MDD) is a common psychiatric disorder and a leading cause of disability worldwide.1 Global estimates of lifetime MDD prevalence range from 2.1% to 21.0%.2 The heritability of MDD is estimated as 37% from a meta-analysis of twin and family studies,3 supporting a complex etiology that includes both genetic and environmental factors. Modelling results suggest that the heritability of MD was not influenced by the duration of the required recall. Kim Finucane Our results are consistent with a polygenic architecture for MDD. 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. PC1 and PC2 were included as covariates. In aggregate, common single-nucleotide polymorphisms (SNPs) explained between 20% and 29% of the variance in MDD risk, and the heritability in MDD explained by each chromosome was proportional to its length (.

JAMA Psychiatry. Results confirm a complex genetic architecture for MDD, supporting etiological mechanisms for both common and rare genetic variation to MDD risk. Gusev The Genetic Architecture of Major Depressive Disorder in Han Chinese Women. Recurrent MDD cases were recruited from 58 provincial mental health centers and psychiatric departments of general medical hospitals in 45 cities and 23 provinces of China. We partitioned SNPs into MAF quintiles (0.005-0.50) and estimated the proportion of variance contributed by each quintile using the multicomponent GREML approach. However, there is also a large proportion of variation in liability left to be explained by nongenetic factors. Clinical characteristics of major depression that predict risk of depression in relatives.  et al. SNP-Based Heritability for MD Subtypes Are Not Significantly Different, eTable 7. The genetic variance of mania explained by common genetic influences with depression was estimated to be 0.25, and the variance explained by specific genetic influences was estimated to be 0.60. 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. Systematic localization of common disease-associated variation in regulatory DNA. This site needs JavaScript to work properly. 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.  A, Brace Background: Major depressive disorder (MDD) is the second largest cause of global disease burden.

All exonic SNPs were annotated using ANNOVAR.18 Variants of each annotation category and in each gene were aggregated for every individual and used in logistic regression as predictors of MDD, controlling for measures associated with sequencing runs, batch, read mapping quality, sequence coverage over the genome, GC (guanine-cytosine) content, PC from the common variant analysis, and city of origin.  PM. 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. 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). J. Husted, C. M. T. Greenwood, A. S.

McClellan Objective: The study protocol was approved by the Ethical Review Board of Oxford University and the ethics committees of all participating hospitals in China.  ET, Goldstein Yet, evidence on whether these subphenotypes are familial or heritable is scarce. BACKGROUND: Major depressive disorder (MDD) is the second largest cause of global disease burden.  Y, Zhan 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. Participants Diagnosed with Major Depressive Disorder and assessed for depressive symptoms before and after prescription of an antidepressant medication. Unipolar depressive disorders have a common genotype. Purcell Cases were recurrent and quite severe, with approximately 85% meeting the criteria for melancholia. Panossian Personality and major depression: a Swedish longitudinal, population-based twin study. 2002 Jul;32(5):829-42. doi: 10.1017/s0033291702005858. Our results apply to Han Chinese women, aged between 30 and 60 years, with recurrent depression.  MC, Prescott Heritability estimates for separate vs joint analyses of all chromosomes indicated a negligible effect of confounding population structure (joint h2 = 21.4%; separate h2 = 23.6%) (eFigure 2 in the Supplement). Edvardsen J, Torgersen S, Røysamb E, Lygren S, Skre I, Onstad S, Øien PA. J Affect Disord.  RM, Weinblatt First, we estimated the lower bound of narrow-sense heritability as between 20% and 29% depending on the method applied and the assumed MDD prevalence.  JL, Fromer Genome-wide Complex Trait Analysis estimates of SNP h2 for major depressive disorder partitioned by minor allele frequency quintile.  et al.  HD, Hesterman Published Online: December 21, 2016. doi:10.1001/jamapsychiatry.2016.3578. We determined 95% CIs for enrichment curves by bootstrapping and assessed significance by empirical null distributions (eAppendix in the Supplement). SIRT1 mediates depression-like behaviors in the nucleus accumbens. 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. Genetic risk for liability to recurrent MDD was partitioned using sparse whole-genome sequencing. Not nearly as prevalent as other forms of depressive disorders. The heritability of Major Depressive Disorder (MDD) has been estimated at 37% based largely on twin studies that rely on contested assumptions. 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. the narrow sense heritability of MDD to be 37%, confirming the involvement of genetic factors in MDD (2). We also found an enrichment of SNPs in DHSs, which mark transcriptionally active regions of the genome, in several tissue types, including brain tissue. 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). Obtained funding: Webb, Riley, Flint, Kendler. 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). Predictive Value of MD Status From BLUP Polygenic Risk Score (PRS) Constructed From Half of the Sample (Sample 1) and Tested in the Remaining 50% (Sample 2), eTable 5.  D.  Population structure and eigenanalysis. All Rights Reserved. Cases were aged between 30 and 60 years and had 2 or more episodes of MDD that met the criteria of the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision),14 with the first episode occurring between ages 14 and 50 years; had not abused drugs or alcohol before their first depressive episode; and reported no history of schizophrenia or mania. Molecular signatures of major depression. Results confirm a complex genetic architecture for MDD, supporting etiological mechanisms for both common and rare genetic variation to MDD risk. Yet, evidence on whether these subphenotypes are familial or heritable is scarce. 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). As we are using imputed SNPs and therefore a denser set of markers than on genotyping arrays, we accounted for the biasing effect of uneven linkage disequilibrium by 2 methods. An important theoretical question is the expected pattern of findings if we selected a more homogeneous and more severely ill cohort. The heritability of major depression has been estimated at 31%−42% (11, 12). Enrichment of SNPs With Small P Values in MD Analysis for DHS in ENCODE Samples, eFigure 4.  D.  Principal components analysis corrects for stratification in genome-wide association studies.  E,  et al; Major Depressive Disorder Working Group of the Psychiatric GWAS Consortium. Examining the occurrence of one or more depressive episodes across all three interviews, heritabilities of MD (95% CI) for the four time periods were: 0.41 (0.27-0.54), 0.41 (0.26-0.55), 0.35 (0.16-0.52) and 0.34 (0.11-0.55). For example, support for the polygenic basis of schizophrenia was demonstrated by the predictive value of polygenic risk scores.8 An alternative genome-wide approach derives narrow-sense heritability of quantitative traits by simultaneously considering all SNPs to estimate additive genetic variance.9 The Cross-Disorder Group of the Psychiatric Genomics Consortium used this approach to estimate SNP-based heritability of MDD at approximately 21%.10 In addition, significant associations with polygenic burden of private disruptive mutations from whole-exome sequencing have been reported for psychiatric disease, including schizophrenia.11. The diagnostic validity of melancholic major depression in a population-based sample of female twins. Importance 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. 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. Specifically, SNPs in genic regions, especially those in introns and 3′ UTR, explain more variance than in noncoding regions.  CO, Neale All participants were Han Chinese women with 4 Han grandparents. Clipboard, Search History, and several other advanced features are temporarily unavailable. Kendler  et al.  PF, Neale Results  Dr Cai is supported by EBI-Sanger Postdoctoral Fellowship. Recently, Finucane et al29 have reported enrichment of functional elements in 17 complex traits and diseases, including 3 psychiatric disorders. Ripke to download free article PDFs, 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. Research is needed to quantify the relative contribution of classes of genetic variation across the genome to inform future genetic studies of MDD. Speed True Positive Rates in the Exomes of Variant Calls Occurring Only Once in the CONVERGE Cohort, eTable 6. Examining burden scores from singleton exonic SNPs predicted to be deleterious indicated that cases had significantly more mutations than controls (odds ratio, 1.009; 95% CI, 1.003-1.014; P = .003), including those occurring in genes expressed in the brain (odds ratio, 1.011; 95% CI, 1.003-1.018; P = .004) and within nuclear-encoded genes with mitochondrial gene products (odds ratio, 1.075; 95% CI, 1.018-1.135; P = .009). Controls were recruited from several locations, including general hospitals and local community centers. Special thanks to all the CONVERGE collaborators and patients who made our work possible.

Singletons (both SNPs and INDELs [insertions and deletions]) were called when 2 or more reads supported the same alternative allele in a single sample. Depression is common and costly, and it is projected to be the second leading cause of disability worldwide by 2020 (7–10).  G, We conducted GWAS of each subset, subsequently performing linkage disequilibrium–based “clumping” to remove highly correlated markers (r2>0.1) while retaining the most significant SNP within 500-kB intervals.  DB. © 2021 American Medical Association.  H, Hemingway Uncovering the roles of rare variants in common disease through whole-genome sequencing.
