In a subsequent study in Portuguese children by the same group, the presence of jhp0562 alone (jhp0562-positive/β-(1,3)galT-negative) was associated with peptic ulcers, whereas the presence of β-(1,3)galT alone (jhp0562-negative/β-(1,3)galT-positive) was associated with gastritis [11]. This evidence concerns the gene GALT and Peptic ulcer.
