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.9524G>A (p.Arg3175His) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00028 in 246978 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in CDH23 causing Usher Syndrome (0.00028 vs 0.0032), allowing no conclusion about variant significance. c.9524G>A has been reported in the literature in individuals affected with Usher Syndrome or non-syndromic hearing loss (e.g. Astuto_2002, Usami_2008, Cabanillas_2018). These report(s) do not provide unequivocal conclusions about association of the variant with Usher Syndrome. At least two publications report experimental evidence evaluating an impact on protein function (e.g. Yonezawa_2006, Takahashi_2016), suggesting that the variant does not alter protein localization but may impact microtubule formation. However, these findings do not allow convincing conclusions about the variant effect. The following publications have been ascertained in the context of this evaluation (PMID: 12075507, 29986705, 27349180, 18368581, 16281288). Six submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as VUS (n=5) and likely benign (n=1). Based on the evidence outlined above, the variant was classified as uncertain significance. -
