Genes affected

OTOS (HGNC:22644): (otospiralin) Otospiralin is synthesized by nonsensory cells (fibrocytes) of the inner ear, and downregulation of otospiralin in guinea pigs leads to deafness (Lavigne-Rebillard et al., 2003 [PubMed 12687421]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Dec 02, 2022

The c.233G>A (p.S78N) alteration is located in exon 4 (coding exon 3) of the OTOS gene. This alteration results from a G to A substitution at nucleotide position 233, causing the serine (S) at amino acid position 78 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
