Genes affected

STRC (HGNC:16035): (stereocilin) This gene encodes a protein that is associated with the hair bundle of the sensory hair cells in the inner ear. The hair bundle is composed of stiff microvilli called stereocilia and is involved with mechanoreception of sound waves. This gene is part of a tandem duplication on chromosome 15; the second copy is a pseudogene. Mutations in this gene cause autosomal recessive non-syndromic deafness. [provided by RefSeq, Jul 2008]

The p.Asn297Ser variant in STRC has not been previously reported in individuals with hearing loss. Data from large population studies is insufficient to assess the frequency of this variant. Computational prediction tools and conservation a nalysis suggest that this variant may impact the protein, though this informatio n is not predictive enough to determine pathogenicity. In summary, the clinical significance of the p.Asn297Ser variant is uncertain. -
