Gene-environment interaction and psychiatric disorders: Review and future directions

TLDR
After reviewing evidence from candidate GxE studies and presenting alternative theoretical frameworks underpinning GXE research, more recent approaches and findings from whole genome approaches are presented and it is suggested how future Gx E studies may unpick the complex interplay between genes and environments in psychiatric disorders.

No Support for Historical Candidate Gene or Candidate Gene-by-Interaction Hypotheses for Major Depression Across Multiple Large Samples.

TL;DR: The results suggest that early hypotheses about depression candidate genes were incorrect and that the large number of associations reported in the depression candidate gene literature are likely to be false positives.

Mental Well-Being (Depression, Loneliness, Insomnia, Daily Life Fatigue) during COVID-19 Related Home-Confinement—A Study from Poland

TL;DR: Women had higher mean scores of depression, loneliness, and daily life fatigue and more often than males started exercising and there were more cases of increased alcohol consumption than among students.
Journal ArticleDOI

Environment, lifestyle, and Parkinson's disease: Implications for prevention in the next decade.

TL;DR: A number of low‐risk and potentially high‐yield recommendations for lifestyle modification could be made to minimize the individual and societal burdens of Parkinson's disease, including dietary modifications, increasing physical activity, and head injury avoidance.
Journal ArticleDOI

Genetics of Resilience: Gene-by-Environment Interaction Studies as a Tool to Dissect Mechanisms of Resilience.

TL;DR: It is argued that the principle used in gene-by-environment interaction studies may help to unravel resilience mechanisms on different investigation levels and is presented how this could be achieved by top-down designs that start with gene- by- environment interaction effects on disease phenotypes as well as by bottom-up approaches that start at the molecular level.

Lifetime and 12-Month Prevalence of DSM-III-R Psychiatric Disorders in the United States: Results From the National Comorbidity Survey

TL;DR: The prevalence of psychiatric disorders is greater than previously thought to be the case, and morbidity is more highly concentrated than previously recognized in roughly one sixth of the population who have a history of three or more comorbid disorders.

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.

Biological insights from 108 schizophrenia-associated genetic loci

TL;DR: Associations at DRD2 and several genes involved in glutamatergic neurotransmission highlight molecules of known and potential therapeutic relevance to schizophrenia, and are consistent with leading pathophysiological hypotheses.

Association of Anxiety-Related Traits with a Polymorphism in the Serotonin Transporter Gene Regulatory Region

TL;DR: The short variant of the polymorphism reduces the transcriptional efficiency of the 5-HTT gene promoter, resulting in decreased 5HTT expression and 5HT uptake in lymphoblasts as discussed by the authors, which is the site of action of widely used uptake-inhibiting antidepressant and antianxiety drugs.

Common polygenic variation contributes to risk of schizophrenia and bipolar disorder

TL;DR: The extent to which common genetic variation underlies the risk of schizophrenia is shown, using two analytic approaches, and the major histocompatibility complex is implicate, which is shown to involve thousands of common alleles of very small effect.
