Genes affected

WHRN (HGNC:16361): (whirlin) This gene is thought to function in the organization and stabilization of sterocilia elongation and actin cystoskeletal assembly, based on studies of the related mouse gene. Mutations in this gene have been associated with autosomal recessive non-syndromic deafness and Usher Syndrome. Alternative splicing results in multiple transcript variants.

The p.Ser333Asn variant in DFNB31 has not been previously reported in individual s with hearing loss, but has been identified in 13/66006 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP r s200073414). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational predic tion tools and conservation analysis suggest that the p.Ser333Asn variant may no t impact the protein, though this information is not predictive enough to rule o ut pathogenicity. In summary, the clinical significance of the p.Ser333Asn varia nt is uncertain. -
