ABSTRACT
Objective To examine the correlation between the gene of phosphate and tension homology deleted on chromosometen (PTEN gene) polymorphism and schizophrenia (SCZ) associated with the type 2 diabetes mellitus (T2DM ) in Shanghai Han population. Methods The study recruited 591 long-stay schizophrenic inpatients including 304 with and 287 without type 2 diabetes mellitus, 206 patients with the type 2 diabetes mellitus and 205 normal subjects from Shanghai Han population. SNPs of PTEN gene (rs1234225, rs12569998, rs1234223) were genotyped by using Taqman genotyping. The frequency distributions of allele, genotype and haplotype between groups were analyzed. Results There were significant differences in the frequency of rs1234223 genotype (P=0.01) and allele distribution (P=0.02) between the SCZ with type 2 diabetes mellitus group and the SCZ without type 2 diabetes mellitus group. The difference of genotype frequencies remained statistically significant (P=0.03) but the allele distribution was not (P=0.06) after Bonferroni correction. Haplotype analysis showed that TTC haplotype was less common in the SCZ with type 2 diabetes mellitus group than in the SCZ without type 2 diabetes mellitus group (P=0.02). Conclusions PTEN gene may be a susceptibility gene for schizophrenia with type 2 diabetes mellitus in Chinese Han population. The TTC haplotype may be a protective factor for schizophrenia with type 2 diabetes mellitus.
