摘要
应用PCR扩增HLADQA1基因第二外显子多态区基因片段,γ32P末端标记9个序列特异性寡核苷酸(SSO)进行斑点杂交,本文首次对98例中国人Ⅱ型糖尿病(NIDDM)与HLA的关联进行研究,结果显示NIDDM全组及常见型亚组0401等位基因频率均较正常对照组显著减少,PC值分别小于0.01和0.05,RR0.247,这与IDDM中DQA1等位基因频率的变化不同,提示NIDDM与HLA确有关联,但和IDDM发病与HLA的关联并不相同。
The association of HLA DQA1gene with type 2 diabetes (NIDDM) was investigated in 132 unrelated chinese subjects(98 NIDDM and 34 normal controls). After amplification with polymorase chain reaction, the fragment of second exon polymorphic region of HLA DQA1gene was hybridized with 9 sequence specific oligonucleotide(SSO) labeled with γ 32 P ATP. The result showed that the frequency of allele 0401 decreased significantly in NIDDM whole group(T group) and A group(NIDDM patients whose age of onset was over 65 yr) (P C<0.01 and 0.05 respectively, RR=0.24). The clinical phenotype of NIDDM A group was consistent with typical NIDDM so that it might be exactly to say that HLA DQA1 gene was associated with NIDDM, and DQA1 0401 might protect individuals from development of NIDDM.
