消化性溃疡是最常见的胃肠道疾病之一,病因复杂。最近,我们进行了十二指肠溃疡的全基因组关联研究,并确定了疾病的易感性变化在两个遗传位点对应的前列腺干细胞抗原(PSCA)基因和ABO血型(ABO)基因。在此,我们在两个日本病例对照样本集中调查了这些变异与胃溃疡的关系,共4,291例胃溃疡病例和22,665例对照。因此,在加性模型中,PSCA的rs2294008的C等位基因增加了胃溃疡的风险,比值比(OR)为1.13(P值为5.85×10−7)。另一方面,ABO上的SNP rs505922在两个队列之间表现出不一致的结果。我们的发现意味着在胃和十二指肠溃疡的发病机制中存在共同的遗传变异。
Peptic ulcer is one of the most common gastrointestinal disorders with complex etiology. Recently we conducted the genome wide association study for duodenal ulcer and identified disease susceptibility variations at two genetic loci corresponding to the Prostate stem cell antigen (PSCA) gene and the ABO blood group (ABO) gene. Here we investigated the association of these variations with gastric ulcer in two Japanese case-control sample sets, a total of 4,291 gastric ulcer cases and 22,665 controls. As a result, a C-allele of rs2294008 at PSCA increased the risk of gastric ulcer with odds ratio (OR) of 1.13 (P value of 5.85×10−7) in an additive model. On the other hand, SNP rs505922 on ABO exhibited inconsistent result between two cohorts. Our finding implies presence of the common genetic variant in the pathogenesis of gastric and duodenal ulcers.
