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]

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]

RPL22P17 (HGNC:36985): (ribosomal protein L22 pseudogene 17)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.54).
