Association of TGFB1 polymorphisms to the absence (stages I, II and III) or presence (stage IV) of metastasis in gastric adenocarcinoma patients: SNP rs1800468‐G/A showed a significant augment in patients with metastasis (type IV) compared to non‐metastatic ones (stage I, II and III, OR 3.71 P = .04). The gene discussed is TGFB1; the disease is gastric adenocarcinoma.
