To account for effects of uneven linkage disequilibrium, we applied the GCTA-LDMS19 and the LDAK17 approaches. A significant enrichment in deleterious variants in nuclear-encoded mitochondrial genes (OR, 1.075; 95% CI, 1.018-1.135; P = .009) was found. Corresponding Author: Kenneth S.

The results suggest … 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. 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. While the 4 brains are among the most enriched tissues for MDD-associated SNPs in DHS, samples from the liver and pancreas also showed comparable enrichment. We tested case-control differences by logistic regression with ancestry PC as covariates.  DB. 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.

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.  ME, Shadick 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).  B, Todd-Brown Error bars represent 95% CIs, ncRNA, non-coding RNA. 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. Uher Modelling results suggest that the heritability of MD was not influenced by the duration of the required recall. A, Aggregate Genome-wide Complex Trait Analysis (GCTA) estimates. All Rights Reserved. We randomly selected an amount of coding DNA equal in length to that used when the analysis is restricted to genes expressed in the brain and in nuclear-encoded mitochondrial genes and then repeated the analyses 10 000 times. Exon coordinates contained 96 130 824 base pair positions in 254 986 exons in 21 946 genes.  PF.

Importance  When partitioning SNPs into 3′-UTR, 5′-UTR, exonic, and intronic regions, those in introns and 3′ UTR were significantly enriched for disease-relevant effects (Figure 2A). 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).  J, Kendler 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). 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. 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.
