Labcorp Genetics (formerly Invitae), Labcorp RCV000698666 SCV000827346 uncertain significance 3-methylcrotonyl-CoA carboxylase 1 deficiency 2023-05-11 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with MCCC1-related conditions. 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on MCCC1 protein function. ClinVar contains an entry for this variant (Variation ID: 576221). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 408 of the MCCC1 protein (p.Pro408Ser).
