Thirty-eight polymorphisms in 10 genes determined by mass spectrometry assay served as candidate drivers of arsenic-induced pigmentary changes. Urine and plasma arsenic levels were determined by inductively coupled plasma mass spectrometry. Hair arsenic concentrations were measured by nondispersive atomic fluorescence spectrometry. Arsenic metabolites in urine were determined using high-pressure liquid chromatography hyphenated with hydride generation and inductively coupled plasma mass spectrometry. Serum folate was measured using a folate radioassay kit. Analysis of variance, nonparametric test, or the chi-square test was selected according to the data distribution. Spearman correlation analysis was used to determine the correlation between two parameters. Logistic regression was used to estimate the effect size of SNPs.\u0000 \u0000 \u0000 \u0000 The arsenic concentrations in urine, plasma, and hair and the urine arsenic species were not significantly different between cases and controls. Logistic regression revealed that among the polymorphisms, the methionine synthase (MTR) rs1805087 polymorphism showed a protective effect against arsenic-related pigmentary changes. In the codominant model, the adjusted odds ratio for age, sex, and ethnicity was 0.41 (95% CI, 0.21–0.80; P = 0.008) for the AG genotype and 0.11 (95%CI, 0.02–0.60; P = 0.012) for the GG genotype.\u0000 \u0000 \u0000 \u0000 \u0000 MTR polymorphism showed a protective effect against arsenic-related pigmentary changes in the logistic regression model. The effect of MTR rs1805087 might be independent of arsenic metabolism and one-carbon metabolism.
