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 Uncertain_significance. Variant got 4 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 0.0164 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage

Variant classified as Uncertain Significance - Favor Pathogenic. The p.His503fs variant in ESRRB has not been previously reported in individuals with hearing lo ss or in large population studies. This variant is located in the last exon and is predicted to cause a frameshift. It is predicted to alter the protein?s amin o acid sequence beginning at position 503 and lead to a termination codon 40 ami no acids downstream from the canonical termination codon, thus resulting in a pr otein 34 amino acids longer than the normal one. Therefore, the impact of this variant on the protein function is unknown. In summary, while there is some sus picion for a pathogenic role, the clinical significance of the p.His503fs varian t is uncertain. -
