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]

The c.7C>A (p.Q3K) alteration is located in exon 2 (coding exon 1) of the SLCO1B1 gene. This alteration results from a C to A substitution at nucleotide position 7, causing the glutamine (Q) at amino acid position 3 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
