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]

Likely benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 28, 2017This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
not specified Benign:2
Benign, criteria provided, single submitterclinical testingGeneDxMay 16, 2014This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpNov 12, 2018Variant summary: SLC22A5 c.1645C>T (p.Pro549Ser) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0072 in 277216 control chromosomes in the gnomAD database, including 83 homozygotes. The observed variant frequency is approximately 2-folds higher than the estimated maximal expected allele frequency for a pathogenic variant in SLC22A5 causing Systemic Primary Carnitine Deficiency phenotype (0.0046), strongly suggesting that the variant is benign. c.1645C>T has been reported in the literature in individuals affected with Systemic Primary Carnitine Deficiency . These report(s) do not provide unequivocal conclusions about association of the variant with Systemic Primary Carnitine Deficiency . Multiple functional studies, Amat di San Filippo_2008, Frigeni_2017, Urban_2006, found the variant to act comparable to wild type function. Two ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant as likely benign/benign. Based on the evidence outlined above, the variant was classified as benign. -
