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]

Benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 13, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpApr 18, 2016Variant summary: The c.807A>G variant affects a non-conserved nucleotide, resulting in synonymous amino acid change. Mutatation Taster predicts polymorphism outcome for this variant. 5/5 splice-site tools via Alamut predict that this variant does not affect the consensus splice donor site though it may create a cryptic splice donor site as predicted by 3/5 tools. However, in silico prediction results are not definite and there are no functional studies to confirm this. This variant is found in 53257/121244 control chromosomes (12476 homozygotes) from the large and broad populations of ExAC at a frequency of 0.4392547, which is about 96 times greater than the maximal expected frequency of a pathogenic allele (0.0045644) in this gene. Thus this variant is a common polymorphism found in general population. In one family, this variant was found in cis with a potentially pathogenic variant p.Leu476Arg in homozygous state in two affected siblings and was found in homozygous state in the unaffected father of the siblings (Mutlu-Albayrak_2015) -- an evidence of lack of cosegregation which further supports the benign outcome. One clinical laboratory has classified this variant as benign. Taken together, this variant has been classified as Benign. -
