Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the AQP5 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000001651.4. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Forms a water-specific channel. Implicated in the generation of saliva, tears, and pulmonary secretions. Required for TRPV4 activation by hypotonicity (PubMed:16571723). Together with TRPV4, controls regulatory volume decrease in salivary epithelial cells (PubMed:16571723). {ECO:0000269|PubMed:16571723}.;
Disease
DISEASE: Keratoderma, palmoplantar, Bothnian type (PPKB) [MIM:600231]: A dermatological disorder characterized by diffuse non-epidermolytic hyperkeratosis of the skin of palms and soles. PPKB is frequently complicated by fungal infections. {ECO:0000269|PubMed:23830519}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
Pathway
