Targeted pharmacogenetic analysis of antipsychotic response in the CATIE study.

ABSTRACT:

Aim

This study evaluated the impact of 6789 SNPs on treatment response to antipsychotics in Caucasian patients from the CATIE study.

Materials & methods

An Illumina (CA, USA) BeadChip was designed that targeted genes potentially impacting disease risk, disease presentation or antipsychotic response. SNPs tagged regions of linkage disequilibrium or functional variants not detectable using previous genotypes for CATIE. Change in Positive and Negative Syndrome scale total score was modeled using a mixed model repeated measures method that assumed a 30-day lag period. Genetic association analysis was performed using linear regression.

Results

Association analysis identified 20 SNPs with p-values of ≤5 × 10(-4). Many of these are in genes previously implicated in schizophr
