Genes affected

AS3MT (HGNC:17452): (arsenite methyltransferase) AS3MT catalyzes the transfer of a methyl group from S-adenosyl-L-methionine (AdoMet) to trivalent arsenical and may play a role in arsenic metabolism (Lin et al., 2002 [PubMed 11790780]).[supplied by OMIM, Mar 2008]

The c.349T>C (p.Y117H) alteration is located in exon 5 (coding exon 5) of the AS3MT gene. This alteration results from a T to C substitution at nucleotide position 349, causing the tyrosine (Y) at amino acid position 117 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
