Previous genome-wide association studies (GWAS) suggest that rs10489202 in the intron of MPC2 (mitochondrial pyruvate carrier 2) is a risk locus for schizophrenia in Han Chinese populations.
This study aimed to test the association between the NKAPL rs1635, TSPAN18 rs11038167, and MPC2rs10489202 polymorphisms and SZ in a Chinese population.
The results showed that rs10489202 in MPC2 (BRP44) is significantly associated with schizophrenia in these East Asian replication samples (one-tailed P=5.75×10(-3), OR=1.12), and further meta-analysis after including previous GWAS data yielded a genome-wide significant association (two-tailed P=1.11×10(-10), OR=1.19), adding further support for the involvement of this locus in the genetic risk of schizophrenia, and future studies regarding the underlying molecular mechanisms of the risk association are necessary.
A recent genome-wide association study (GWAS) of Han Chinese identified a single-nucleotide polymorphism (SNP, rs10489202) in the mitochondrial pyruvate carrier 2 gene (MPC2, also known as BRP44) as a possible susceptibility locus for schizophrenia.
