Interaction of theADRB2Gene Polymorphism With Childhood Trauma in Predicting Adult Symptoms of Posttraumatic Stress Disorder

AssociationN=2,893Israel Liberzon et al.(2014)· JAMA Psychiatry

This genetic association study identified ADRB2 SNP rs2400707 as protective against PTSD symptoms in the context of childhood adversity (β=0.243, P=1.02×10^-5 in discovery cohort; P=0.0009 in replication cohort). The AA homozygotes showed lower PTSD severity with ≥2 categories of adverse childhood experiences across two independent cohorts (n=810 soldiers and n=2,083 civilians), with combined interaction effect P=3.97×10^-7. The protective A allele tags the H1 haplotype, hypothesized to represent low-transcription ADRB2 variant.

About ADRB2

This gene encodes beta-2-adrenergic receptor which is a member of the G protein-coupled receptor superfamily. This receptor is directly associated with one of its ultimate effectors, the class C L-type calcium channel Ca(V)1.2. This receptor-channel complex also contains a G protein, an adenylyl cyclase, cAMP-dependent kinase, and the counterbalancing phosphatase, PP2A. The assembly of the signaling complex provides a mechanism that ensures specific and rapid signaling by this G protein-coupled receptor. This receptor is also a transcription regulator of the alpha-synuclein gene, and together, both genes are believed to be associated with risk of Parkinson's Disease. This gene is intronless. Different polymorphic forms, point mutations, and/or downregulation of this gene are associated with nocturnal asthma, obesity, type 2 diabetes and cardiovascular disease.
