Those affected may also occasionally have delusions or hallucinations. © 2021 American Medical Association. 2009 Sep;117(1-2):30-41. doi: 10.1016/j.jad.2008.12.004. BACKGROUND: Major depressive disorder (MDD) is the second largest cause of global disease burden. All participants provided written informed consent. Data collection took place from August 1, 2008, to October 31, 2012. Exon coordinates contained 96 130 824 base pair positions in 254 986 exons in 21 946 genes. Details on DNA sequencing and imputation of genotypes have been previously reported5 and are summarized in the eAppendix in the Supplement.

Husted, C. M. T. Greenwood, A. S. Bassett, Heritability of schizophrenia and major affective disorder as a function of age, in the presence of strong cohort effects, European Archives of Psychiatry and Clinical Neuroscience, 10.1007/s00406-005-0629-z, 256, 4, (222-229), (2005). 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). It has an estimated heritability of 37%, but published genome-wide association studies have so far identified few risk loci.  A, Baselmans However, on splitting the sample, symptoms in children (aged 8 to 11) could be explained by shared environmental factors only, while symptoms in adolescents (aged 11 to 16) remained highly heritable. 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).  WK, Rasgon Yang We identified all SNPs with association P values with MDD less than threshold values (−log10[p] = 0, 0.5, 1, 1.5, …), and then we computed the proportion of SNPs lying in DHSs. 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. Design, Setting, and Participants   JL, SNP-Based Heritability Estimates by Major Depression Population Prevalence, eTable 2a. 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.  DB.  MR, Balding A, Aggregate Genome-wide Complex Trait Analysis (GCTA) estimates. Using sparse whole-genome sequencing, we detected and replicated 2 common variants that contribute to MDD risk.5 Not unexpectedly, these genome-wide significant loci accounted for only a small fraction of variance in MDD liability (approximately 0.6%). A Swedish national twin study of lifetime major depression. Screened controls (n = 5196) were recruited from a range of locations, including general hospitals and local community centers. Conflict of Interest Disclosures: None reported. 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. 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. 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).  et al. Objectives  Loh Depression is common and costly, and it is projected to be the second leading cause of disability worldwide by 2020 (7–10). 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. Dr Bacanu is supported by NIH grants R21MH100560 and R21AA022717. 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.  R, Rynes Could the estimates of heritability of MD be biased by the well-demonstrated genetic influences on memory? ENCODE Project Consortium. It has an estimated heritability of 37% but published genome-wide association studies have so … Kendler 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. 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.  NA, Reich  G, Results support a complex etiology for MDD and highlight the value of analyzing components of heritability to clarify genetic architecture. Genetic variants associated with subjective well-being, depressive symptoms, and neuroticism identified through genome-wide analyses. SNPs were mapped to 3′- or 5′-UTR, exonic, or intronic regions of known protein-coding genes or intergenic and ncRNA regions. Nakahata Ferrari  G, Gusev 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. © 2021 American Medical Association.

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. Permutations were performed to verify that P values were not inflated (eAppendix in the Supplement). Arch Gen Psychiatry. Data were collected from August 1, 2008, to October 31, 2012.

Our results apply to Han Chinese women, aged between 30 and 60 years, with recurrent depression. 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 (. 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. We tested case-control differences by logistic regression with ancestry PC as covariates. To apply aggregate genetic risk methods to clarify the genetic architecture of MDD by estimating and partitioning heritability by chromosome, minor allele frequency, and functional annotations and to test for enrichment of rare deleterious variants. Common polygenic variation contributes to risk of schizophrenia and bipolar disorder. Accepted for Publication: October 23, 2016. Data for the whole sample were best explained by an additive genetic model, with heritability of depressive symptom scores estimated at 79%. This model fit the data well, and the heritability of melancholia was not different from nonmelancholic MDD, as expected under the liability threshold model. 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.

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. NIH Heritability, though, isn’t a guarantee that you will develop this illness.  NJ, Plenge  L, Fenik  MC, Kendler BACKGROUND: Major depressive disorder (MDD) is the second largest cause of global disease burden. Yet, evidence on whether these subphenotypes are familial or heritable is scarce. Customize your JAMA Network experience by selecting one or more topics from the list below. Partitioning heritability of regulatory and cell-type-specific variants across 11 common diseases. Satoh This could mean that in most cases of depression, around 50% of the cause is genetic, and around 50% is unrelated to genes (psychological or physical factors). Research is needed to quantify the relative contribution of classes of genetic variation across the genome to inform future genetic studies of MDD. Second, our results support a substantial polygenic component to the risk of MDD involving many alleles of individually very small effect. 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.  KS.  EJ. A significant proportion of variance was due to common variants, although rare variation also appears to contribute to MDD disease liability. Because these tests explore whether the 2 ORs are significantly different, we applied a Bonferroni corrected threshold of 0.025 (0.05/2).
