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.Gly146Arg variant in STRC has not been previously reported in individuals with hearing loss. Data from large population studies are insufficient to asses s the frequency of this variant. Computational prediction tools and conservatio n analyses do not provide strong support for or against an impact to the protein . In summary, the clinical significance of the Gly146Arg variant is uncertain. -
