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.622G>A (p.G208S) alteration is located in exon 8 (coding exon 8) of the AS3MT gene. This alteration results from a G to A substitution at nucleotide position 622, causing the glycine (G) at amino acid position 208 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
