Labcorp Genetics (formerly Invitae), Labcorp RCV001884297 SCV002153529 uncertain significance Methylmalonic acidemia with homocystinuria, type cblX 2021-10-19 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 affected with HCFC1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with methionine at codon 387 of the HCFC1 protein (p.Val387Met). The valine residue is highly conserved and there is a small physicochemical difference between valine and methionine.
