Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000216452 SCV000271550 uncertain significance not specified 2015-08-11 criteria provided, single submitter clinical testing The c.1515-12G>A variant in CDH23 has not been previously reported in individual s with hearing loss or Usher syndrome, but has been identified in 1/26694 Europe an chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinsti tute.org; rs369396703). Although this variant has been seen in the general popu lation, its frequency is not high enough to rule out a pathogenic role. This var iant is located in the 3' splice region. Computational tools suggest an impact to splicing. However, this information is not predictive enough to determine pat hogenicity. In summary, the clinical significance of the c.1515-12G>A variant is uncertain.
GeneDx RCV000486086 SCV000564845 likely pathogenic not provided 2013-10-29 criteria provided, single submitter clinical testing The c.1515-12 G>A splice site variant in the CDH23 gene has not been reported as a pathogenic variant or as a benign polymorphism to our knowledge. In silico algorithms predict that the c.1515-12G>A variant create an upstream cryptic splice acceptor site that is stronger than the wild-type splice acceptor site. One in silico algorithm also predicted that the wild-type splice acceptor site is destroyed. The c.1515-12 G>A variant was not observed at any significant frequency in approximately 6,200 individuals of European and African American ancestry in an external variant database. The c.1515-12 G>A variant in the CDH23 gene is a strong candidate for a pathogenic, although the possibility that it is a benign polymorphism cannot be completed excluded.
