For ALDH2 rs671, the risk of NPC was higher for study subjects with the AA/AG alleles compared with subjects with the GG allele, whether alcohol was consumed (OR = 1.47; 95% CI = 0.95–2.27, p = 0.082) or not (1.27; 0.97–1.67, p = 0.087). The gene discussed is ALDH2; the disease is nasopharyngeal carcinoma.
