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]

AS3MT links:

BORCS7-ASMT (HGNC:49183): (BORCS7-ASMT readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring C10orf32 (chromosome 10 open reading frame 32) and AS3MT (arsenic, +3 oxidation state, methyltransferase) genes. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is therefore unlikely to produce a protein product. [provided by RefSeq, Dec 2010]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1034A>G (p.D345G) alteration is located in exon 11 (coding exon 11) of the AS3MT gene. This alteration results from a A to G substitution at nucleotide position 1034, causing the aspartic acid (D) at amino acid position 345 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
