Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_022124.6(CDH23):c.3328A>G(p.Ser1110Gly) variant causes a missense change. The variant allele was found at a frequency of 0.0000143 in 1,613,042 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1110R) has been classified as Likely benign.

ClinVar
Submissions by phenotype
not specified Uncertain:1
The p.Ser1110Gly variant in CDH23 has not been previously reported in individual s with hearing loss, but has been identified in 2/60180 of European (Non-Finnish ) chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstit ute.org). Computational prediction tools and conservation analysis do not provid e strong support for or against an impact to the protein. In summary, the clinic al significance of the p.Ser1110Gly variant is uncertain. -
Usher syndrome type 1D Uncertain:1
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
Usher syndrome type 1 Uncertain:1
- -
not provided Uncertain:1
This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 1110 of the CDH23 protein (p.Ser1110Gly). This variant is present in population databases (rs757508152, gnomAD 0.006%). 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: 228492). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CDH23 protein function with a negative predictive value of 95%. 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. -
