Oleastro et al. found the presence of jhp0562 alone (jhp0562-positive/β-(1,3)galT-negative) was associated with peptic ulcers, rather than with gastritis, and the presence of β-(1,3)galT alone (jhp0562-negative/β-(1,3)galT-positive) was associated with gastritis, rather than with peptic ulcers [16]. This evidence concerns the gene GALT and peptic ulcer disease.
