ABSTRACT
The associations of four single nucleotide polymorphisms (p.Arg194Trp, p.Arg280His, p.Pro206Pro, and p.Arg399Gln) in X-ray repair cross-complementing group 1 with urinary arsenic metabolites and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were investigated in a Vietnamese population (n = 100). Individuals with genotype AA in p.Pro206Pro showed significantly higher urinary monomethylarsonic acid (MMA(V)) and lower dimethylarsinic acid (DMA(V))/MMA(V) ratio than genotype AG. As for p.Arg399Gln, both Arg/Arg homozygous subjects and Arg/Gln heterozygous individuals showed a significantly higher urinary inorganic As percentage and lower 8-OHdG concentrations than Gln/Gln homozygous. Our results suggested that Arg399Gln is a functional SNP that may be related to DNA repair activity.
