Poor replication of candidate genes for major depressive disorder using genome-wide association data

TLDR
Support for involvement in MDD for only four genes is found, which may point to publication bias and false-positive findings in previous candidate gene studies, and may also be related to heterogeneity of the MDD phenotype as well as contextual genetic or environmental factors.

A Critical Review of the First 10 Years of Candidate Gene-by-Environment Interaction Research in Psychiatry

TL;DR: Gene-by-environment interaction studies in psychiatry have typically been conducted using a candidate G×E (cG×E) approach, analogous to the candidate gene association approach used to test genetic main effects, yet cG–E findings remain controversial.

Inflammatory cytokines in depression: Neurobiological mechanisms and therapeutic implications

TL;DR: This review explores the idea that specific gene polymorphisms and neurotransmitter systems can confer protection from or vulnerability to specific symptom dimensions of cytokine-related depression and potential therapeutic strategies that target inflammatory cytokine signaling.

Gene × Environment Interaction Studies Have Not Properly Controlled for Potential Confounders: The Problem and the (Simple) Solution

TL;DR: This manuscript demonstrates that the practice of improperly controlling for covariates is the norm in the G × E interaction literature to date and shows that many alternative explanations for G ×E findings that investigators had thought were eliminated have not been.
Journal ArticleDOI

The genetics of major depression.

TL;DR: Genome-wide association and linkage results provide constraints on the allele frequencies and effect sizes of susceptibility loci, which are used to interpret the voluminous candidate gene literature.

PLINK: A Tool Set for Whole-Genome Association and Population-Based Linkage Analyses

TL;DR: This work introduces PLINK, an open-source C/C++ WGAS tool set, and describes the five main domains of function: data management, summary statistics, population stratification, association analysis, and identity-by-descent estimation, which focuses on the estimation and use of identity- by-state and identity/descent information in the context of population-based whole-genome studies.

Genome-wide association study of 14,000 cases of seven common diseases and 3,000 shared controls

TL;DR: This study has demonstrated that careful use of a shared control group represents a safe and effective approach to GWA analyses of multiple disease phenotypes; generated a genome-wide genotype database for future studies of common diseases in the British population; and shown that, provided individuals with non-European ancestry are excluded, the extent of population stratification in theBritish population is generally modest.

TL;DR: This article reports that the magazine's award for Research Leader of the Year was given to the Wellcome Trust Case Control Consortium which conducted a huge genetic study to look at the genetic causes for various diseases.

A new multipoint method for genome-wide association studies by imputation of genotypes

TL;DR: This work proposes a coherent analysis framework that treats the genome-wide association problem as one involving missing or uncertain genotypes, and proposes a model-based imputation method for inferring genotypes at observed or unobserved SNPs, leading to improved power over existing methods for multipoint association mapping.
