ABSTRACT
<p><b>OBJECTIVE</b>To observe the association between single nucleotide polymorphism (SNP) of peroxisome proliferators-activated receptor-gamma coactivator-1alpha (PGC-1alpha ) gene and type 2 diabetes mellitus(T2DM).</p><p><b>METHODS</b>Four common SNPs of PGC-1alpha gene were genotyped with polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and then analyzed with transmission-disequilibrium test (TDT) and sib transmission-disequilibrium test (STDT) in 69 T2DM pedigrees (310 individuals). Furthermore, the authors performed a case-control study to genotype Gly482Ser in 156 patients with T2DM and 111 normal glucose tolerance people without family history.</p><p><b>RESULTS</b>(1)There were no positive results in four variances in TDT-STDT analysis(P> 0.05). (2)The Gly482Ser exhibited a significant difference between the two groups. GA genotype carriers were at increased risk for T2DM (OR=1.85), and there was statistically significant difference in the allele frequency between the case and control groups(P=0.046). (3) The subjects with GG genotype at position Gly482Ser had a higher HDL-C and lower LDL-C and TG levels when compared against those with GA+AA genotype in the control group without family history(P=0.043,lzP=0.046, P=0.037 respectively).</p><p><b>CONCLUSION</b>This study suggested that the PGC-1alpha gene might be implicated in the pathogenesis of T2DM. But the studied SNPs in PGC-1alpha gene may not be major susceptibility ones of T2DM mellitus in Han people of Shanghai.</p>
