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.

Computational evidence support a benign effect (BayesDel_noAF=-0.46).

BP6

Variant 9-114423332-G-C is Benign according to our data. Variant chr9-114423332-G-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 45658.

BP7

Synonymous conserved (PhyloP=0.494 with no splicing effect.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000302 (46/152206) while in subpopulation EAS AF = 0.00834 (43/5158). AF 95% confidence interval is 0.00636. There are 0 homozygotes in GnomAd4. There are 24 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 3 AR gene
