Genes affected

ESRRB (HGNC:3473): (estrogen related receptor beta) This gene encodes a protein with similarity to the estrogen receptor. Its function is unknown; however, a similar protein in mouse plays an essential role in placental development. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 14-76482717-C-T is Pathogenic according to our data. Variant chr14-76482717-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 517379.Status of the report is criteria_provided_single_submitter, 1 stars.

The p.Arg249X variant in ESRRB has not been previously reported in individuals w ith hearing loss and is absent from large population studies. This nonsense vari ant leads to a premature termination codon at position 249 which is predicted to lead to a truncated or absent protein. Loss of function variants in ESRRB have been associated with autosomal recessive sensorineural hearing loss, however the exact mechanism of disease has not yet been established. In summary, although a dditional studies are required to fully establish its clinical significance, the p.Arg249X variant is likely pathogenic. -
