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]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Met417Ilefs*106) in the SLC22A5 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 141 amino acid(s) of the SLC22A5 protein. This variant is present in population databases (rs781330134, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with SLC22A5-related conditions. ClinVar contains an entry for this variant (Variation ID: 503649). This variant disrupts a region of the SLC22A5 protein in which other variant(s) (p.Asp519Thrfs*7) have been determined to be pathogenic (internal data). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
