Genes affected

SLC14A2 (HGNC:10919): (solute carrier family 14 member 2) The protein encoded by this gene belongs to the urea transporter family. In mammalian cells, urea is the chief end product of nitrogen catabolism, and plays an important role in the urinary concentration mechanism. This protein is expressed in the inner medulla of the kidney, and mediates rapid transepithelial urea transport across the inner medullary collecting duct. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2011]

The c.1345C>A (p.P449T) alteration is located in exon 10 (coding exon 9) of the SLC14A2 gene. This alteration results from a C to A substitution at nucleotide position 1345, causing the proline (P) at amino acid position 449 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
