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.3293A>G (p.Asn1098Ser) 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 0.0023 in 247856 control chromosomes, predominantly at a frequency of 0.0039 within the Non-Finnish European subpopulation in the gnomAD database, including one homozygote. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 1.2 fold of the estimated maximal expected allele frequency for a pathogenic variant in CDH23 causing Usher Syndrome phenotype (0.0032). To our knowledge, no occurrence of c.3293A>G in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 45913). Based on the evidence outlined above, the variant was classified as likely benign. -
