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 classified as Uncertain Significance - Favor Benign. The p.Ala376Ser var iant in WHRN has not been previously reported in individuals with hearing loss, but has been identified in 0.09% (28/30778) of South Asian chromosomes including 1 homozygote by the Genome Aggregation Database (gnomAD, http://gnomad.broadins titute.org; dbSNP rs545251395). Computational prediction tools and conservation analysis suggest that the p.Ala376Ser variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary , while the clinical significance of the p.Ala376Ser variant is uncertain, avail able data suggest that this variant is more likely to be benign. ACMG/AMP criter ia applied: BP4 -
