Genes affected

SLC22A5 (HGNC:10969): (solute carrier family 22 member 5) Polyspecific organic cation transporters in the liver, kidney, intestine, and other organs are critical for elimination of many endogenous small organic cations as well as a wide array of drugs and environmental toxins. The encoded protein is a plasma integral membrane protein which functions both as an organic cation transporter and as a sodium-dependent high affinity carnitine transporter. The encoded protein is involved in the active cellular uptake of carnitine. Mutations in this gene are the cause of systemic primary carnitine deficiency (CDSP), an autosomal recessive disorder manifested early in life by hypoketotic hypoglycemia and acute metabolic decompensation, and later in life by skeletal myopathy or cardiomyopathy. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Apr 2015]

Review Status: criteria provided, single submitter

This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 19 of the SLC22A5 protein (p.Arg19Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with carnitine deficiency (PMID: 11715001). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 25351). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt SLC22A5 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects SLC22A5 function (PMID: 11715001, 16652335, 28841266). For these reasons, this variant has been classified as Pathogenic. -
