Applying a multilevel approach, we analyzed the main and interactive effects of the functional COMT val158met polymorphism and L-dopa (single-dose 50 mg levodopa and 12.5 mg carbidopa; double-blind, placebo-controlled design) on the emotion-potentiated (unpleasant, neutral, and pleasant IAPS pictures) startle response as an intermediate phenotype of anxiety in a sample of 100 healthy probands (f = 52, m = 48).

Results indicate a main as well as a GxE effect of the COMT Val158Met variant and childhood maltreatment on the affect-modulated startle reflex, supporting a complex pathogenetic model of the affect-modulated startle reflex as a basic neurobiological defensive reflex potentially related to anxiety and affective disorders.

The present results provide further support for a-potentially female-specific-role of the COMT val158met polymorphism in the genetic and neural underpinnings of anxiety- and depression-related intermediate phenotypes and may aid in further clarifying the differential role of COMT genotype driven dopaminergic tonus in the processing of emotionally salient stimuli.

Many of these differences are unconfirmed or minor, but some appear to be of reasonable robustness and magnitude; eg the functional Val(158)Met polymorphism in COMT is associated with obsessive-compulsive disorder in men, with anxiety phenotypes in women, and has a greater impact on cognitive function in boys than girls.

The paper focuses on such candidate gene polymorphisms that alter alcoholism-related intermediate phenotypes including: dopaminergic system polymorphic variants (DRD2 -141C Ins/Del in promoter region, exon 8 and DRD2 TaqI A and DAT 40bp VNTR genes polymorphisms) that cause predisposition to severe alcoholism (haplotype Ins/G/A2); COMT Val158Met gene polymorphism related to differences in executive cognitive function and 5-HTT gene promoter polymorphism, which alters stress response and affects anxiety and dysphoria.
