}}[[rs1522305]] is a SNP in the phenylalanine hydroxylase ([[PAH]]) gene.

A study of Caucasian cohorts, Bulgarian families, and African American families concluded that the more common [[rs1522305]](G) allele was associated in the first two populations with increased risk for [[schizophrenia]]. {{PMID|18937293|OA=1
