Updated meta-analysis of CMYA5 rs3828611 and rs4704591 with schizophrenia in Asian populations.

ABSTRACT

AIM: Two single-nucleotide polymorphisms, rs3828611 and rs4704591, in the cardiomyopathy-associated protein 5 (CMYA5) gene have been extensively investigated for associations with schizophrenia in Asian populations, but with conflicting results. To assess the collective evidence across individual studies, we conducted an updated meta-analysis. METHODS: We performed a random-effect model meta-analysis of the associations of rs3828611 and rs4704591 with schizophrenia using seven case-control samples from Asian populations (8074 patients and 8139 controls). RESULTS: The meta-analysis indicated that rs3828611 and rs4704591 were not significantly associated with schizophrenia (odds ratios [OR] = 0.93, 95% confidence interval [CI] = 0.85-1.01 and OR = 0.99, 95% CI = 0.93-1.05, respectively). CONCLUSIONS: Our meta-analysis did not provide evidence supporting a contribution of CMYA5 rs3828611 and rs4704591 to schizophrenia susceptibility in Asian populations.
