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)

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM1
In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 6 uncertain in NM_000486.6
PM2
Very rare variant in population databases, with high coverage;
PP3
MetaRNN computational evidence supports a deleterious effect, 0.986
PP5
Variant 12-49954647-C-G is Pathogenic according to our data. Variant chr12-49954647-C-G is described in ClinVar as Pathogenic. ClinVar VariationId is 17839.Status of the report is no_assertion_criteria_provided, 0 stars.
