Submissions by phenotype
not provided Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jul 17, 2022 | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 2845 of the CDH23 protein (p.Arg2845His). This variant is present in population databases (rs199668532, gnomAD 0.005%). 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: 179385). 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 C0"). 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. - |

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Nov 22, 2013 | The Arg2845His variant in CDH23 has not been previously reported in individuals with hearing loss but has been reported in 1/1152 (0.2%) chromosomes from a broa d population by the CLINSEQ project (dbSNP rs199668532). Computational analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT ) do not provide strong support for or against an impact to the protein. In summ ary, additional data is needed to determine the clinical significance of this va riant. - |
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 21, 2024 | The c.8534G>A (p.R2845H) alteration is located in exon 59 (coding exon 58) of the CDH23 gene. This alteration results from a G to A substitution at nucleotide position 8534, causing the arginine (R) at amino acid position 2845 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
