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]

Variant classified as Uncertain Significance - Favor Benign. The p.Pro158Leu var iant in EDNRB has not been previously reported in individuals with hearing loss, Waardenburg syndrome, or Hirschsprung disease, or in large population studies. The proline (Pro) at position 158 is not conserved across species, including ma mmals. Of note, two mammals (elephant and manatee) have a leucine (Leu) at this position despite high nearby amino acid sequence conservation. Additional comp utational prediction tools suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the p.Pro158Leu variant is uncertain , these data suggest it is more likely to be benign. -
