Genes affected
AQP6 (HGNC:639): (aquaporin 6) The protein encoded by this gene is an aquaporin protein, which functions as a water channel in cells. Aquaporins are a family of small integral membrane proteins related to the major intrinsic protein (MIP or AQP0). This protein is specific for the kidney. This gene and related family members AQP0, AQP2, and AQP5 reside in a cluster on chromosome 12q13. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.329G>A (p.G110E) alteration is located in exon 1 (coding exon 1) of the AQP6 gene. This alteration results from a G to A substitution at nucleotide position 329, causing the glycine (G) at amino acid position 110 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
