RCV001228251 | SCV001400641 | pathogenic | not provided | 2024-08-06 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Leu305Cysfs*8) 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 (no rsID available, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with Usher syndrome (PMID: 25468891). ClinVar contains an entry for this variant (Variation ID: 955581). For these reasons, this variant has been classified as Pathogenic. |

RCV002298910 | SCV002598940 | likely pathogenic | Usher syndrome | 2022-09-12 | criteria provided, single submitter | clinical testing | Variant summary: CDH23 c.913delC (p.Leu305CysfsX8) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncating variants downstream of this variant have been associated with Usher syndrome in HGMD. The variant allele was found at a frequency of 4e-06 in 249214 control chromosomes. c.913delC has been reported in the literature as a complex heterozygote in at least one individual with clinically diagnosed Usher Syndrome (Bujakowska_2014). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic. |
