Invitae RCV000707552 SCV000836653 uncertain significance Interstitial lung and liver disease; Charcot-Marie-Tooth disease, axonal, type 2u 2018-04-28 criteria provided, single submitter clinical testing This sequence change replaces lysine with glutamic acid at codon 456 of the MARS protein (p.Lys456Glu). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with MARS-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; 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.
