Labcorp Genetics (formerly Invitae), Labcorp RCV001890746 SCV002148558 uncertain significance 3-methylcrotonyl-CoA carboxylase 1 deficiency 2021-09-29 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 C15"). This missense change has been observed in individual(s) with 3MCC deficiency (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamic acid with lysine at codon 234 of the MCCC1 protein (p.Glu234Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine.
