Labcorp Genetics (formerly Invitae), Labcorp RCV001067196 SCV001232242 uncertain significance Methylmalonic acidemia with homocystinuria, type cblJ 2019-03-14 criteria provided, single submitter clinical testing 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. 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"). This variant has not been reported in the literature in individuals with ABCD4-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces tyrosine with histidine at codon 476 of the ABCD4 protein (p.Tyr476His). The tyrosine residue is highly conserved and there is a moderate physicochemical difference between tyrosine and histidine.
