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 GeneticsApr 23, 2024The c.218G>T (p.W73L) alteration is located in exon 4 (coding exon 4) of the AS3MT gene. This alteration results from a G to T substitution at nucleotide position 218, causing the tryptophan (W) at amino acid position 73 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
