Genes affected

SLCO1B1 (HGNC:10959): (solute carrier organic anion transporter family member 1B1) This gene encodes a liver-specific member of the organic anion transporter family. The encoded protein is a transmembrane receptor that mediates the sodium-independent uptake of numerous endogenous compounds including bilirubin, 17-beta-glucuronosyl estradiol and leukotriene C4. This protein is also involved in the removal of drug compounds such as statins, bromosulfophthalein and rifampin from the blood into the hepatocytes. Polymorphisms in the gene encoding this protein are associated with impaired transporter function. [provided by RefSeq, Mar 2009]

Pathogenic, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Jul 09, 2020	- -
Pathogenic, criteria provided, single submitter	clinical testing	3billion	-	The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.006%). The variant is predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. The variant has been reported at least twice as pathogenic without evidence for the classification (ClinVar ID: VCV000030439 / PMID: 22232210). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -
Pathogenic, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Dec 09, 2022	Variant summary: SLCO1B1 c.757C>T (p.Arg253X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 6e-05 in 251156 control chromosomes (gnomAD). This frequency does not allow conclusions about the variant significance. SLCO1B1 c.757C>T (p.Arg253X) (along with SLCO1B3, c.1747+1G>A) has been reported in the literature in individuals affected with Rotor Syndrome which supports the digenic recessive inheritance of the disease (examples: van de Steeg_2012, Chen_2019, and Zhou_2020). It has been shown that digenic pathogenic variants in SLCO1B1 and SLCO1B3 cause Rotor syndrome (GeneReviews, NCBI Bookshelf). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
