schizophrenia. However, response is highly variable and possible genetic underpinnings of
this variability remain unknown. Here, we performed polygenic risk score (PRS) analyses to
estimate the amount of variance in symptom severity among clozapine-treated patients
explained by PRSs (R2) and examined the association between symptom severity and
genotype-predicted CYP1A2, CYP2D6, and CYP2C19 enzyme activity. Genome-wide …
