Genes affected

SLC22A3 (HGNC:10967): (solute carrier family 22 member 3) 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. This gene is one of three similar cation transporter genes located in a cluster on chromosome 6. The encoded protein contains twelve putative transmembrane domains and is a plasma integral membrane protein. [provided by RefSeq, Jul 2008]

The c.457A>C (p.M153L) alteration is located in exon 2 (coding exon 2) of the SLC22A3 gene. This alteration results from a A to C substitution at nucleotide position 457, causing the methionine (M) at amino acid position 153 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
