Genes affected

OTOGL (HGNC:26901): (otogelin like) The protein encoded by this gene belongs to the otogelin family. This gene is expressed in the inner ear of vertebrates with the highest level of expression seen at the embryonic stage and lowest in adult. Knockdown studies in zebrafish suggest that this gene is essential for normal inner ear function. Mutations in this gene are associated with autosomal recessive deafness.

The p.Trp4X variant in OTOGL has been identified in a compound heterozygous stat e in 1 individual with hearing loss, who also carried an additional loss-of-func tion variant in OTOGL (LMM data). It has also been identified in 1/6086 African chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinsti tute.org; dbSNP rs1191512072), which is low enough to be consistent with a reces sive carrier frequency. This nonsense variant leads to a premature termination c odon at position 4, which is predicted to lead to a truncated or absent protein. Loss of function of the OTOGL gene is an established disease mechanism in autos omal recessive hearing loss. In summary, although additional studies are require d to fully establish its clinical significance, the p.Trp4X variant is likely pa thogenic. ACMG/AMP Criteria applied: PVS1; PM2_Supporting; PM3. -
