ADH1B and Parkinson disease: Jimenez-Jimenez et al. analyzed the possible relationship of two common SNPs (rs6413413 and rs1229984) in ADH1B with the risk for RLS or Parkinson’s disease and found that rs1229984 SNP was associated with the risk for not only RLS [23], but also with the risk for Parkinson’s disease in women [24].
