Genes affected

MAT2B (HGNC:6905): (methionine adenosyltransferase 2 non-catalytic beta subunit) The protein encoded by this gene belongs to the methionine adenosyltransferase (MAT) family. MAT catalyzes the biosynthesis of S-adenosylmethionine from methionine and ATP. This protein is the regulatory beta subunit of MAT. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Nov 2012]

The c.758A>G (p.N253S) alteration is located in exon 6 (coding exon 6) of the MAT2B gene. This alteration results from a A to G substitution at nucleotide position 758, causing the asparagine (N) at amino acid position 253 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
