Genes affected

EDNRB (HGNC:3180): (endothelin receptor type B) The protein encoded by this gene is a G protein-coupled receptor which activates a phosphatidylinositol-calcium second messenger system. Its ligand, endothelin, consists of a family of three potent vasoactive peptides: ET1, ET2, and ET3. Studies suggest that the multigenic disorder, Hirschsprung disease type 2, is due to mutations in the endothelin receptor type B gene. Alternative splicing and the use of alternative promoters results in multiple transcript variants. [provided by RefSeq, Oct 2016]

The c.1195-10C>A variant in EDNRB has not been previously reported in individual s with hearing loss. Data from large population studies are insufficient to asse ss the frequency of this variant. This variant is located in the 3' splice regio n. Computational tools do not suggest an impact to splicing. However, this infor mation is not predictive enough to rule out pathogenicity. In summary, the clini cal significance of the c.1195-10C>A variant is uncertain. -
