Genes affected

MSRB3 (HGNC:27375): (methionine sulfoxide reductase B3) The protein encoded by this gene catalyzes the reduction of methionine sulfoxide to methionine. This enzyme acts as a monomer and requires zinc as a cofactor. Several transcript variants encoding two different isoforms have been found for this gene. One of the isoforms localizes to mitochondria while the other localizes to endoplasmic reticula. [provided by RefSeq, Jul 2010]

Ambry Genetics

Aug 04, 2024

The c.73G>T (p.A25S) alteration is located in exon 1 (coding exon 1) of the MSRB3 gene. This alteration results from a G to T substitution at nucleotide position 73, causing the alanine (A) at amino acid position 25 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
