RCV001245578 | SCV001418875 | uncertain significance | not provided | 2022-03-10 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 426 of the CDH23 protein (p.Arg426Cys). This variant is present in population databases (rs373674747, gnomAD 0.004%). 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: 970077). 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 C65"). 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. |

RCV004821302 | SCV005442576 | uncertain significance | Autosomal recessive nonsyndromic hearing loss 12 | 2024-12-15 | criteria provided, single submitter | research | The CDH23 c.1276C>T:p.(Arg426Cys) variant, predicted deleterioos, is very rare. It was detected in an individual with sloping normal-to-severe hearing loss that carried an additional variant in another USH gene, MYO7A c.535A>G:p.(Ser179Gly). Both genes are known to be involved in NSHL as well as in USH syndrome. The hearing loss in this case might be caused by digenic inheritance of the two variants. ; |
