The study tested the differences of the combined genotypes of the predisposing SNPs in integrin α5β1 encoding genes ITGA5, ITGB1 -1949 and ITGB1 +31804, implicating the influence of integrin α5β1 on host-bacterial interaction processes during gastric carcinogenesis, between the children of GCA and DU controls (Table 2). The gene discussed is ITGA5; the disease is temporal arteritis.
