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.

Uncertain significance, criteria provided, single submitter	clinical testing	Eurofins Ntd Llc (ga)	Mar 20, 2018	- -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 06, 2022	In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Nov 29, 2022	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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 180026). This variant has not been reported in the literature in individuals affected with WHRN-related conditions. This variant is present in population databases (rs534523640, gnomAD 0.04%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 687 of the WHRN protein (p.Pro687Leu). -

The p.Pro687Leu variant in DFNB31 has not been previously reported in individual s with hearing loss and was absent from large population studies. Computational prediction tools and conservation analyses suggest that the p.Pro687Leu variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the p.Pro687Leu variant is uncertain. -
