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]
EDNRB-AS1 (HGNC:49045): (EDNRB antisense RNA 1)

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 16640). This premature translational stop signal has been observed in individual(s) with EDNRB-related conditions (PMID: 11891690). This variant is present in population databases (rs104894391, gnomAD 0.0009%). This sequence change creates a premature translational stop signal (p.Arg201*) in the EDNRB gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in EDNRB are known to be pathogenic (PMID: 8001159, 10528251, 20127975, 30394532). -
