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]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 11, 2022This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 46 of the CDH23 protein (p.Thr46Met). This variant is present in population databases (no rsID available, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with CDH23-related conditions. ClinVar contains an entry for this variant (Variation ID: 618008). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitterclinical testingARUP Laboratories, Molecular Genetics and Genomics, ARUP LaboratoriesFeb 02, 2018The p.Thr46Met variant has not been reported in the medical literature, gene specific variation databases, nor has it been previously identified by our laboratory. This variant is listed in the Genome Aggregation Database (gnomAD) with a frequency of 0.01 percent in the African population (identified on 3 out of 24,026 chromosomes). The threonine at position 46 is moderately conserved considering 12 species (Alamut v2.10) and computational analyses of the effects of the p.Thr46Met variant on protein structure and function provide conflicting results (SIFT: tolerated, MutationTaster: disease causing, PolyPhen-2: probably damaging). Altogether, there is not enough evidence to classify the p.Thr46Met variant with certainty. -
