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.

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.1963C>T (p.P655S) alteration is located in exon 18 (coding exon 18) of the OTOGL gene. This alteration results from a C to T substitution at nucleotide position 1963, causing the proline (P) at amino acid position 655 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
