  1. SNP: single nucleotide polymorphism; AS3MT: (+ 3 oxidative state) methylation transferase; TAs: total arsenic; iAsIII%: inorganic arsenite/TAs × 100%; iAsV%: inorganic arsenate/TAs × 100%; MMA%: monomethylarsonic acid/TAs × 100%; DMA%: dimethylarsinic acid/TAs × 100%. PMI: primary methylation index; SMI: secondary methylation index
  2. aAll the other SNPs of AS3MT showed no significant influence on arsenic metabolism, therefore only A9749G and A27215G are presented
