AimPrevious evidence has found that some single nucleotide polymorphisms (SNPs) in cardiomyopathy-associated 5 gene (CMYA5) were associated with schizophrenia in the Caucasian and Chinese Han populations. In this study, we aimed to investigate the relationship between CMYA5 gene polymorphisms and schizophrenia in Chinese Uygur population and perform a meta-analysis to synthetically analyse the association of CMYA5 gene polymorphisms with schizophrenia in Asian populations.
MethodWe retrospectively analysed 985 schizophrenia cases and 1123 healthy controls in Chinese Uygur population. Four SNPs (rs259127, rs3828611, rs4704591 and rs6883197) of CMYA5 were genotyped using TaqMan SNP genotyping assay. Meta-analysis was conducted across Asian studies by Review Manager 5.2.
ResultsResults showed no significant difference in either allelic or genotypic frequency in four SNPs of the CMYA5 gene between cases and controls (P>0.05). However, the age of onset and the PANSS positive-factor subscale score were significantly lower in schizophrenia patients with the A/A genotype of rs6883197 than those with A/G and G/G genotypes (P<0.05). In addition, the meta-analysis showed the significant association of rs3828611 with risk of schizophrenia (P=0.03, OR=0.92, 95% CI: 0.91-0.99).
ConclusionsOur results support the association between CMYA5rs6883197 and schizophrenia in Chinese Uygur population. Meta-analysis demonstrated that rs3828611 was significantly associated with schizophrenia in Asian population. Genetic heterogeneity among populations may be the main reason of results conflict between studies. In conclusion, association between CMYA5 gene polymorphisms and schizophrenia was confirmed in Asian population.
