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]

This sequence change creates a premature translational stop signal (p.Val153Alafs*41) in the SLC22A5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC22A5 are known to be pathogenic (PMID: 9916797). This variant is present in population databases (rs386134195, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with primary carnitine deficiency (PMID: 15714519). ClinVar contains an entry for this variant (Variation ID: 25376). For these reasons, this variant has been classified as Pathogenic. -

Variant summary: The SLC22A5 c.458_459delTG (p.Val153Alafs) variant results in a premature termination codon, predicted to cause a truncated or absent SLC22A5 protein due to nonsense mediated decay, which are commonly known mechanisms for disease. A truncation downstream of this position, c.760C>T (p.Arg254X), has been classified as pathogenic by our laboratory. This variant is absent in 121412 control chromosomes. The variant of interest has been reported in multiple compound heterozygous affected individual via a publication (Dobrowolski_2005) and a database (ARUP). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as "likely pathogenic/pathogenic." Taken together, this variant has been classified as pathogenic. -
