Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000039163	SCV000062847	pathogenic	Rare genetic deafness	2012-05-29	criteria provided, single submitter	clinical testing	The Arg1236X variant in CDH23 has not been reported in the literature nor previo usly identified by our laboratory. This nonsense variant leads to a premature te rmination codon at position 1236, which is predicted to lead to a truncated or a bsent protein. In summary, this variant meets our criteria to be classified as p athogenic (http://pcpgm.partners.org/LMM).
GeneDx	RCV000482326	SCV000567002	pathogenic	not provided	2015-06-30	criteria provided, single submitter	clinical testing	The R1236X nonsense variant in the CDH23 gene is predicted to cause loss of normal protein functioneither through protein truncation or nonsense-mediated mRNA decay. The R1236X variant was notobserved in approximately 6,200 individuals of European and African American ancestry in the NHLBIExome Sequencing Project, indicating it is not a common benign variant in these populations. Although thisvariant has not been reported previously to our knowledge, we consider it to be pathogenic.

Invitae	RCV000482326	SCV004637744	pathogenic	not provided	2023-10-09	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Arg1236*) 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 (rs397517327, gnomAD 0.003%). 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: 45929). For these reasons, this variant has been classified as Pathogenic.
