Genes affected

MAT2A (HGNC:6904): (methionine adenosyltransferase 2A) The protein encoded by this gene catalyzes the production of S-adenosylmethionine (AdoMet) from methionine and ATP. AdoMet is the key methyl donor in cellular processes. [provided by RefSeq, Jun 2011]

The p.E10Q variant (also known as c.28G>C), located in coding exon 1 of the MAT2A gene, results from a G to C substitution at nucleotide position 28. The glutamic acid at codon 10 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
