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.

Variant summary: WHRN c.2332C>T (p.Arg778X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein. The variant allele was found at a frequency of 4e-06 in 250230 control chromosomes (gnomAD). c.2332C>T has been reported in the literature in multiple individuals affected with deafness and the variant segregated with the disease (example: Mburu_2003). These data indicate that the variant is very likely to be associated with disease. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change creates a premature translational stop signal (p.Arg778*) in the WHRN gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in WHRN are known to be pathogenic (PMID: 12833159, 15841483, 22147658). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 2689). This premature translational stop signal has been observed in individual(s) with non-syndromic deafness (PMID: 12833159). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. -
