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)

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Arg343Gln variant in EDNRB has not been previously reported in individuals with hearing loss, but has been identified in several populations including 5/1 26336 European chromosomes by the Genome Aggregation Database (gnomAD, http://gn omad.broadinstitute.org; dbSNP rs140514830). Although this variant has been seen in the general population, its frequency is not high enough to rule out a patho genic role. Computational prediction tools and conservation analysis suggest tha t the p.Arg343Gln variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical signi ficance of the p.Arg343Gln variant is uncertain. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 253 of the EDNRB protein (p.Arg253Gln). This variant is present in population databases (rs140514830, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with EDNRB-related conditions. ClinVar contains an entry for this variant (Variation ID: 504854). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt EDNRB protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
