Variant summary

Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PS3PM2PP3_StrongPP5_Very_Strong

The NM_022124.6(CDH23):​c.5712G>A​(p.Thr1904Thr) variant causes a splice region, synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,613,038 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000062908: exon-trapping assays reveal that the variant causes skipping of exon 43 which does not result in the disruption of the reading frame (von Brederlow 2002 PMID:11857743)." and additional evidence is available in ClinVar.

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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 18 ACMG points.

PS3
PS3 evidence extracted from ClinVar submissions: SCV000062908: exon-trapping assays reveal that the variant causes skipping of exon 43 which does not result in the disruption of the reading frame (von Brederlow 2002 PMID: 11857743).; SCV002241130: Studies have shown that this variant results in skipping of exon 42, but is expected to preserve the integrity of the reading-frame (PMID: 11857743).; SCV004739382: "In vitro exon skipping experiments showed that the c.5712G>A variant results in skipping of exon 43, which does not alter the reading frame but would result in the loss of 70 amino acids (von Brederlow et al. 2002. PubMed ID: 11857743)."
PM2
Very rare variant in population databases, with high coverage;
PP3
Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. Scorers claiming Uncertain: max_spliceai. No scorers claiming Benign.
PP5
Variant 10-71785100-G-A is Pathogenic according to our data. Variant chr10-71785100-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 45989.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
