Labcorp Genetics (formerly Invitae), Labcorp RCV002000886 SCV002274761 uncertain significance 3-methylglutaconic aciduria, type VIIB 2021-04-09 criteria provided, single submitter clinical testing This variant is present in population databases (rs767839493, ExAC 0.002%). This sequence change replaces aspartic acid with valine at codon 641 of the CLPB protein (p.Asp641Val). The aspartic acid residue is moderately conserved and there is a large physicochemical difference between aspartic acid and valine. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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.
