Genes affected

SLC22A2 (HGNC:10966): (solute carrier family 22 member 2) 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. It is found primarily in the kidney, where it may mediate the first step in cation reabsorption. [provided by RefSeq, Jul 2008]

The c.1195G>A (p.D399N) alteration is located in exon 7 (coding exon 7) of the SLC22A2 gene. This alteration results from a G to A substitution at nucleotide position 1195, causing the aspartic acid (D) at amino acid position 399 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
