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]

Pathogenic, criteria provided, single submitterclinical testingGeneDxFeb 25, 2019The c.9629_9632delTCAA variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). It causes a frameshift starting with codon Isoleucine 3210, changes this amino acid to an Arginine residue and creates a premature Stop codon at position 5 of the new reading frame, denoted p.Ile3210ArgfsX5. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. We interpret this variant as pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 22, 2024This sequence change creates a premature translational stop signal (p.Ile3210Argfs*5) in the CDH23 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CDH23 are known to be pathogenic (PMID: 11138009, 21940737). This variant is present in population databases (rs397517367, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with Usher syndrome (PMID: 33111992). ClinVar contains an entry for this variant (Variation ID: 46077). For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMay 08, 2012The Ile3210Argfs variant in CDH23 has not been reported in the literature. The v ariant is predicted to alter the protein?s amino acid sequence beginning at posi tion 3210 and lead to a premature termination codon 5 amino acids downstream. Th is alteration is then predicted to lead to a truncated or absent protein. In sum mary, this variant meets our criteria to be classified as pathogenic. -
