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.

Oct 13, 2023

The c.77T>C (p.L26S) alteration is located in exon 2 (coding exon 2) of the OTOGL gene. This alteration results from a T to C substitution at nucleotide position 77, causing the leucine (L) at amino acid position 26 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
