ALDH3A1 and myelodysplastic syndrome: Our results show that ALDH3A1 (rs2228100) CG genotype was associated with MN and MDS development (MN: OR=2.072, 95%CI 1.197–3.585, p = 0.009; MDS: OR = 2.204, 95%CI 1.119–4.344, p = 0.022), while GG carriers have 3.4x lower risk of MN development (OR = 0.296, 95%CI 0.105–0.828, p = 0.02).
