Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV002222949 SCV002500332 uncertain significance not specified 2022-03-11 criteria provided, single submitter clinical testing Variant summary: CDH23 c.1888G>C (p.Glu630Gln) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 246648 control chromosomes. c.1888G>C has been reported in the literature as a homozygous genotype in at-least one individual with Usher Syndrome type 1D (example, Sloan-Heggen_2016) who was also likely included in a subsequent study of individuals with cochlear implants who underwent testing on the identical genetic panel, namely OtoSCOPE (University of Iowa) (example, Yoon_2020). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic.
