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.

This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 566 of the WHRN protein (p.Val566Leu). This variant is present in population databases (rs189654215, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with WHRN-related conditions. ClinVar contains an entry for this variant (Variation ID: 45662). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.

Review Status:criteria provided, single submitter
Collection Method:clinical testing

Val566Leu in exon 8 of DFNB31: This variant is not expected to have clinical sig nificance because dog, cat, cow, chicken, frog, elephant, and opossum have a leu cine at this position despite high nearby amino acid conservation. The Val566Leu variant occurs in the third to last three base of the exon which is part of the splicing consensus sequence. However, splicing prediction programs suggest no i mpact to splicing.
