Labcorp Genetics (formerly Invitae), Labcorp RCV002286628 SCV003259666 likely pathogenic Renal carnitine transport defect 2022-09-20 criteria provided, single submitter clinical testing This variant disrupts the p.Ala301 amino acid residue in SLC22A5. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 11058897). 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 SLC22A5 protein function. This variant has not been reported in the literature in individuals affected with SLC22A5-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.06%). This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 301 of the SLC22A5 protein (p.Ala301Gly). 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.
