Invitae | RCV001362548 | SCV001558572 | uncertain significance | 3-methylglutaconic aciduria, type VIIB | 2020-08-26 | criteria provided, single submitter | clinical testing | This sequence change replaces cysteine with phenylalanine at codon 704 of the CLPB protein (p.Cys704Phe). The cysteine residue is moderately conserved and there is a large physicochemical difference between cysteine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with CLPB-related conditions. 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: "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. |
