Does Childhood Trauma Moderate Polygenic Risk for Depression? A Meta-analysis of 5765 Subjects From the Psychiatric Genomics Consortium

TLDR
In this paper, the meta-analytic evidence for interaction between major depressive disorder (MDD) and childhood trauma (CT) was found, which suggests that the previously reported interaction effects, although both statistically significant, can best be interpreted as chance findings.

Polygenic risk scores: from research tools to clinical instruments

TL;DR: How polygenic risk score may be informative at different points in the disease trajectory is considered giving examples of progress in the field and discussing obstacles that need to be addressed before clinical implementation.

The Devastating Clinical Consequences of Child Abuse and Neglect: Increased Disease Vulnerability and Poor Treatment Response in Mood Disorders

TL;DR: The persistent alterations associated with childhood maltreatment are summarized, including alterations in the hypothalamic-pituitary-adrenal axis and inflammatory cytokines, which may contribute to disease vulnerability and a more pernicious disease course.

Reviewing the genetics of heterogeneity in depression: operationalizations, manifestations and etiologies.

TL;DR: Recent efforts to identify depression subtypes using clinical and data-driven approaches are reviewed, differences in genetic architecture of depression across contexts are examined, and it is argued that heterogeneity in operationalizations of depression is likely a considerable source of inconsistency.

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.

A Map of Human Genome Variation From Population-Scale Sequencing

TL;DR: The 1000 Genomes Project aims to provide a deep characterization of human genome sequence variation as a foundation for investigating the relationship between genotype and phenotype as mentioned in this paper, and the results of the pilot phase of the project, designed to develop and compare different strategies for genomewide sequencing with high-throughput platforms.

Influence of Life Stress on Depression: Moderation by a Polymorphism in the 5-HTT Gene

TL;DR: Evidence of a gene-by-environment interaction is provided, in which an individual's response to environmental insults is moderated by his or her genetic makeup.

Second-generation PLINK: rising to the challenge of larger and richer datasets

TL;DR: The second-generation versions of PLINK will offer dramatic improvements in performance and compatibility, and for the first time, users without access to high-end computing resources can perform several essential analyses of the feature-rich and very large genetic datasets coming into use.
