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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.922G>T (p.A308S) alteration is located in exon 7 (coding exon 6) of the SLC14A2 gene. This alteration results from a G to T substitution at nucleotide position 922, causing the alanine (A) at amino acid position 308 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
