Abstract
AIM: To study the genetic susceptibility of HLA-DQA1 alleles to duodenal ulcer in Wuhan Hans. METHODS: Seventy patients with duodenal ulcer and fifty health y controls were examined for HLA-DQA1 genotypes. HLA-DQA1 typing was carried out by digesting the locus specific polymerase chain reaction amplified products with alleles specific restriction enzymes (PCR-RFLP), i.e. Apal I, Bsaj I, Hph I, Fok I, Mbo II and Mnl I.
RESULTS: The allele frequencies of DQA1*0301 and DQA1*0102 in patients with duodenal ulcer were significantly higher and lower respectivel y than those in healthy controls (0.40 vs 0.20, P = 0.003, Pc orret = 0.024) and (0.05 vs 0.14, P = 0.012, but P corret > 0.05), respectively.
CONCLUSION: DQA1*0301 is a susceptible gene for duodenal ulcer in Wuhan Hans, and there are immunogenetic differences in HLA-DQA1 locus between duodenal ulcer patients and healthy controls.
