Genes affected

CDH23 (HGNC:13733): (cadherin related 23) This gene is a member of the cadherin superfamily, whose genes encode calcium dependent cell-cell adhesion glycoproteins. The encoded protein is thought to be involved in stereocilia organization and hair bundle formation. The gene is located in a region containing the human deafness loci DFNB12 and USH1D. Usher syndrome 1D and nonsyndromic autosomal recessive deafness DFNB12 are caused by allelic mutations of this cadherin-like gene. Upregulation of this gene may also be associated with breast cancer. Alternative splice variants encoding different isoforms have been described. [provided by RefSeq, May 2013]

ACMG classification

Specifications for CDH23 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.38).

BP6

Variant 10-71777709-G-A is Benign according to our data. Variant chr10-71777709-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 178304.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00304 (462/152216) while in subpopulation AFR AF = 0.0105 (436/41520). AF 95% confidence interval is 0.00969. There are 2 homozygotes in GnomAd4. There are 231 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 2 AR,Unknown gene
