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.

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00115 (173/150058) while in subpopulation NFE AF= 0.0019 (128/67460). AF 95% confidence interval is 0.00163. There are 0 homozygotes in gnomad4. There are 75 alleles in male gnomad4 subpopulation. Median coverage is 28. This position pass quality control queck.
