Variation in the HTR1A and HTR2A genes and social adjustment in depressed patients

Background adjustment is impaired in depressed patients. The difficulty to adjust to social circumstances has been hypothesized to be one of the causes of depression, as well as a consequence of the disorder. Genetic variation in the serotonin transporter gene has been previously associated with social adjustment levels in patients with mood disorders. s estigated whether variations on the HTR1A (rs6295) and HTR2A (rs7997012) genes were associated with levels of social adjustment using the Social Adjustment Scale in two samples of depressed patients (total n=156). s ts carrying the GG genotype of the HTR2A-rs7997012 showed better social adjustment in areas of work and family unit bonding. tions findings did not survive correction for multiple testing and should be interpreted with caution. sion nding is in line with previous observations that have associated the G allele of the HTR2A-rs7997012 with higher rate of antidepressant response. The HTR2A-rs7997012 is worthy of further investigation in studies examining factors that are related to depression course and outcome.
