RCV000532761 | SCV000644147 | likely pathogenic | 3-methylcrotonyl-CoA carboxylase 2 deficiency | 2022-07-05 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. 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) performed at Invitae indicates that this missense variant is expected to disrupt MCCC2 protein function. ClinVar contains an entry for this variant (Variation ID: 467804). This missense change has been observed in individual(s) with 3-methylcrotonyl-CoA carboxylase deficiency (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 484 of the MCCC2 protein (p.Thr484Pro). |
