Abstract:
T) of SNP on the APM1 gene were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay in 75 pedigrees (337 individuals) of type 2 diabetes mellitus. Genehunt software was used to analyze the transmission-disequilibrium (TDT) and to calculate SNP combining haplotypes. Meanwhile, the physiological and biochemical parameters were also determined in the pedigrees of type 2 diabetes mellitus. Results: We found no preferential transmission in the tested binding sites or any haplotypes of SNP in the APM1 gene in the filial generation of type 2 diabetes mellitus. In type 2 diabetes mellitus group, GG genotype had higher body mass index (BMI)(P=0.032) and waist circumference (WC)(P=0.030) compared to CC genotype in the patients with SNP-11377 binding site; patients with G allele had lower levels of high-density lipoprotein cholesterol (HDL-C)(P=0.006)and higher levels of fasting plasma insulin (FINS) (P=0.011) as compared to CC genotype. However, FINS levels (P=0.021) in subjects with CC genotype were significantly lower than those with G allele in healthy control group. For patients with SNP+45 binding site, those with GG genotypes had higher BMI (P=0.036) and lower levels of FINS (P=0.014) than those with TT genotypes in both groups. For patients with SNP+276 binding site, those with GG genotypes had higher BMI(P=0.043) than those with T allele in the control group. Conclusion: The SNP of the APM1 gene is not associated with the pedigrees of type 2 diabetes mellitus, but APM1 gene has influence on the function of insulin B cells and the development of obesity.
