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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.37C>G (p.L13V) alteration is located in exon 2 (coding exon 1) of the OTOS gene. This alteration results from a C to G substitution at nucleotide position 37, causing the leucine (L) at amino acid position 13 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
