AS3MT polymorphisms, arsenic metabolites and pregnancy
Arsenic methylating enzyme (AS3MT) genetic variations and their role in variability of As metabolism were evaluated in population of pregnant/non-pregnant women exposed to low levels of As. We have tested the associations between genotypes/haplotype of seven AS3MT SNPs and As metabolites in urine (methylation efficiency). Significant associations of individual SNPs and protective haplotype with ar
