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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2022The c.556G>A (p.V186I) alteration is located in exon 7 (coding exon 7) of the AS3MT gene. This alteration results from a G to A substitution at nucleotide position 556, causing the valine (V) at amino acid position 186 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
