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]

Variant summary: CDH23 c.7312G>A (p.Glu2438Lys) results in a conservative amino acid change in the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.1e-05 in 369714 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in CDH23 causing Usher Syndrome (4.1e-05 vs 0.0032), allowing no conclusion about variant significance. c.7312G>A has been reported in the literature in compound heterozygous individuals affected with hearing loss (Usami_2022, Miyagawa_2012, Mizutari_2015). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 35020051, 25963016, 22899989). ClinVar contains an entry for this variant (Variation ID: 446449). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
