探索1型糖尿病与10个经验证的2型糖尿病位点的可能关联,即,PPARG、KCNJ 11、WFS1、HNF 1 B、IDE/HHEX、SLC 30 A8、CDKAL 1、CDKN 2 A/B、IGF 2 BP 2和FTO/RPGRIP 1L。研究设计和方法-研究了两个欧洲人群样本:1)一个病例对照队列,包括514名1型糖尿病受试者和2,027名对照受试者; 2)一个家庭队列,包括483名完整的1型糖尿病病例-父母三人组(共997名受影响者)。共13个标签单核苷酸多态性(SNPs)从10个2型糖尿病基因座进行了分析1型糖尿病的关联。研究结果表明,1型糖尿病与10个2型糖尿病位点中的任何一个都没有关联,也没有检测到发病年龄的影响。通过使用Wellcome Trust病例对照联盟的1型糖尿病数据进行联合分析,CDKN 2 A/B位点的SNP rs 1412829接近显著性(P = 0.039)(优势比0.929 [95%CI 0.867-0.995]),其未达到经13次检验调整的统计学显著性阈值(α = 0.00385)。结论:这项研究表明,2型糖尿病基因座在1型糖尿病遗传易感性中没有发挥任何明显的作用。两种疾病不同的分子机制突出了鉴别诊断和不同治疗原则的重要性。
OBJECTIVE—To search for a possible association of type 1 diabetes with 10 validated type 2 diabetes loci, i.e., PPARG, KCNJ11, WFS1, HNF1B, IDE/HHEX, SLC30A8, CDKAL1, CDKN2A/B, IGF2BP2, and FTO/RPGRIP1L. RESEARCH DESIGN AND METHODS—Two European population samples were studied: 1) one case-control cohort of 514 type 1 diabetic subjects and 2,027 control subjects and 2) one family cohort of 483 complete type 1 diabetic case-parent trios (total 997 affected). A total of 13 tag single nucleotide polymorphisms (SNPs) from the 10 type 2 diabetes loci were analyzed for type 1 diabetes association. RESULTS—No association of type 1 diabetes was found with any of the 10 type 2 diabetes loci, and no age-at-onset effect was detected. By combined analysis using the Wellcome Trust Case-Control Consortium type 1 diabetes data, SNP rs1412829 in the CDKN2A/B locus bordered on significance (P = 0.039) (odds ratio 0.929 [95% CI 0.867–0.995]), which did not reach the statistical significance threshold adjusted for 13 tests (α = 0.00385). CONCLUSIONS—This study suggests that the type 2 diabetes loci do not play any obvious role in type 1 diabetes genetic susceptibility. The distinct molecular mechanisms of the two diseases highlighted the importance of differentiation diagnosis and different treatment principles.
