Invitae RCV003508569 SCV004280938 uncertain significance Renal carnitine transport defect 2023-11-29 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 481 of the SLC22A5 protein (p.Val481Phe). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with primary carnitine deficiency and/or SLC22A5-related conditions (PMID: 28841266; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. 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 SLC22A5 protein function. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on SLC22A5 function (PMID: 16931768, 18337137). 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.
