Genes affected

CDH23 (HGNC:13733): (cadherin related 23) This gene is a member of the cadherin superfamily, whose genes encode calcium dependent cell-cell adhesion glycoproteins. The encoded protein is thought to be involved in stereocilia organization and hair bundle formation. The gene is located in a region containing the human deafness loci DFNB12 and USH1D. Usher syndrome 1D and nonsyndromic autosomal recessive deafness DFNB12 are caused by allelic mutations of this cadherin-like gene. Upregulation of this gene may also be associated with breast cancer. Alternative splice variants encoding different isoforms have been described. [provided by RefSeq, May 2013]

LOC124902446 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM4: Nonframeshift variant in NON repetitive region in NM_022124.6. Strenght limited to Supporting due to length of the change: 1aa.
• PP5: Variant 10-71810548-ACCG-A is Pathogenic according to our data. Variant chr10-71810548-ACCG-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 191267.We mark this variant Likely_pathogenic, oryginal submissions are: {Likely_pathogenic=1, Uncertain_significance=2}.

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jun 14, 2022	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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 191267). This variant has not been reported in the literature in individuals affected with CDH23-related conditions. This variant is not present in population databases (gnomAD no frequency). This variant, c.9058_9060del, results in the deletion of 1 amino acid(s) of the CDH23 protein (p.Arg3020del), but otherwise preserves the integrity of the reading frame. -
