}}Female carriers of an [[rs1034428]](T) allele (as oriented in dbSNP) have a 2.19x higher risk for [[schizophrenia]] compared to non-carriers, and a 3.28x higher risk for a non-paranoid phenotype.

This SNP is part of a specific haplotype, [[rs989638]]-[[rs1034428]]-[[rs2227098]] G-T-G (as oriented with respect to dbSNP) with an overall ~2x higher risk in females for [[schizophrenia]] (p=0.0008). {{PMID|18163426}}
