Invitae RCV000689683 SCV000817346 uncertain significance Hepatic methionine adenosyltransferase deficiency 2018-08-20 criteria provided, single submitter clinical testing This sequence change replaces lysine with threonine at codon 97 of the MAT1A protein (p.Lys97Thr). The lysine residue is highly conserved and there is a moderate physicochemical difference between lysine and threonine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with MAT1A-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
