Labcorp Genetics (formerly Invitae), Labcorp RCV002988541 SCV003290233 likely pathogenic Carnitine palmitoyltransferase II deficiency 2022-03-12 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. This variant disrupts the p.Pro50 amino acid residue in CPT2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 7711730, 10090476, 12410208, 12707442, 16996287, 17936304). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 CPT2 protein function. This variant has not been reported in the literature in individuals affected with CPT2-related conditions. 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 50 of the CPT2 protein (p.Pro50Ser).
