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

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0711 CDS is truncated, and there are 2 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 14-76498360-ACGGCC-A is Pathogenic according to our data. Variant chr14-76498360-ACGGCC-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 178970.Status of the report is criteria_provided_single_submitter, 1 stars.

The Thr402fs variant in ESRRB has not been previously reported in individuals wi th hearing loss. This frameshift variant is predicted to alter the protein?s ami no acid sequence beginning at position 402 and lead to a premature termination c odon 9 amino acids downstream. This alteration is then predicted to lead to a tr uncated or absent protein. Loss of function variants in ESRRB have been associat ed with autosomal recessive sensorineural hearing loss, however the exact mechan ism of disease has not yet been established. In summary, this variant is likely to be pathogenic, though additional studies are required to fully establish its clinical significance. -
