Genes affected
AQP2 (HGNC:634): (aquaporin 2) This gene encodes a water channel protein located in the kidney collecting tubule. It belongs to the MIP/aquaporin family, some members of which are clustered together on chromosome 12q13. Mutations in this gene have been linked to autosomal dominant and recessive forms of nephrogenic diabetes insipidus. [provided by RefSeq, Oct 2008]
AQP5-AS1 (HGNC:55474): (AQP5 and AQP2 antisense RNA 2)
