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

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.2112872).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000302 (46/152344) while in subpopulation AFR AF= 0.000866 (36/41582). AF 95% confidence interval is 0.000643. There are 0 homozygotes in gnomad4. There are 25 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.

The Arg3206His variant in CDH23 has not been previously reported in individuals with hearing loss, but has been identified in 0.1% (4/4142) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/ EVS/; dbSNP rs374156784). Computational prediction tools and conservation analys es do not provide strong support for or against an impact to the protein. In sum mary, additional information is needed to determine the clinical significance of this variant. -
