A promoter polymorphism in the serotonin transporter gene has been widely studied in neuropsychiatry. We genotyped the 5‐HTTLPR/rs25531 triallelic polymorphism in 728 schizophrenia cases from the CATIE study and 724 control subjects. In a logistic regression with case/control status as dependent variable and 7 ancestry‐informative principal components as covariates, the effect of 5‐HTTLPR/rs25531 composite genotype was not significant (odds ratio = 1.008, 95% CI 0.868–1.172, P = 0.91). In cases only, 5‐HTTLPR/rs25531 was not associated with neurocognition (summary neurocognitive index P = 0.21, working memory P = 0.32) or symptomatology (PANSS positive P = 0.67 and negative symptoms P = 0.46). We were unable to identify association of the triallelic 5‐HTTLPR with schizophrenia, neurocognition, or core psychotic symptoms even at levels of significance unadjusted for multiple comparisons. © 2010 Wiley‐Liss, Inc.
