Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS2

The NM_005911.6(MAT2A):c.11A>G(p.Gln4Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000131 in 1,604,184 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q4H) has been classified as Uncertain significance.

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]

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 4 of the MAT2A protein (p.Gln4Arg). This variant is present in population databases (no rsID available, gnomAD 0.007%). This missense change has been observed in individual(s) with clinical features of MAT2A-related conditions (internal data). ClinVar contains an entry for this variant (Variation ID: 2810725). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬¨‚Ä†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Ambry Genetics

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.11A>G (p.Q4R) alteration is located in exon 1 (coding exon 1) of the MAT2A gene. This alteration results from a A to G substitution at nucleotide position 11, causing the glutamine (Q) at amino acid position 4 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
