Genes affected

SLC47A2 (HGNC:26439): (solute carrier family 47 member 2) This gene encodes a protein belonging to a family of transporters involved in excretion of toxic electrolytes, both endogenous and exogenous, through urine and bile. This transporter family shares homology with the bacterial MATE (multidrug and toxin extrusion) protein family responsible for drug resistance. This gene is one of two members of the MATE transporter family located near each other on chromosome 17. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.1269C>G (p.I423M) alteration is located in exon 13 (coding exon 13) of the SLC47A2 gene. This alteration results from a C to G substitution at nucleotide position 1269, causing the isoleucine (I) at amino acid position 423 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
