Genes affected

SLC22A13 (HGNC:8494): (solute carrier family 22 member 13) This gene encodes a member of the organic-cation transporter family. It is located in a gene cluster with another member of the family, organic cation transporter like 4. The encoded protein is a transmembrane protein involved in the transport of small molecules. This protein can function to mediate urate uptake and is a high affinity nicotinate exchanger in the kidneys and the intestine. [provided by RefSeq, Sep 2008]

Collection Method: clinical testing

The c.668C>T (p.T223M) alteration is located in exon 4 (coding exon 4) of the SLC22A13 gene. This alteration results from a C to T substitution at nucleotide position 668, causing the threonine (T) at amino acid position 223 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
