Mutations in different regions of adiponectin gene have been reported to be associated with obesity, atherosclerosis and type 2 diabetes mellitus. The present study was aimed to investigate the association among SNP 45 T > G of adiponectin gene and type 2 diabetes in South Indian population. 75 clinically diagnosed case of type 2 diabetes were studied and compared with 75 apparently healthy controls. The genotype frequency of SNP45 T > G in exon 2 of adiponectin gene was determined by PCR based restriction enzyme analysis using the restriction enzyme SmaI. (recognition site: CCC↓GGG). Three kind of genotypes: wild type TT (470 bp), heterozygous type TG (470 bp, 336 bp, 134 bp) and homozygote mutant type GG (336 bp, 134 bp) were studied. A positive association has been found between SNP45 T > G and type 2 diabetes in the study population (P = 0.010, OR = 3.797, 95% CI = 1.312-10.983). Therefore, SNP45T > G in adiponectin gene may be one of the risk factors for type 2 diabetes.
据报道,脂联素基因不同区域的突变与肥胖、动脉粥样硬化和2型糖尿病有关。本研究旨在调查南印度人群中脂联素基因SNP 45 T>G与2型糖尿病之间的关联。研究了75例临床诊断的2型糖尿病病例,并与75名明显健康的对照者进行比较。使用限制性内切酶SmaI(识别位点:CCC↓GGG),通过基于PCR的限制性酶切分析确定脂联素基因外显子2中SNP45 T>G的基因型频率。研究了三种基因型:野生型TT(470 bp)、杂合型TG(470 bp、336 bp、134 bp)和纯合突变型GG(336 bp、134 bp)。在研究人群中发现SNP45 T>G与2型糖尿病之间存在正相关(P = 0.010,OR = 3.797,95% CI = 1.312 - 10.983)。因此,脂联素基因中的SNP45T>G可能是2型糖尿病的危险因素之一。
