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

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BP6: Variant 10-71707066-C-T is Benign according to our data. Variant chr10-71707066-C-T is described in ClinVar as [Benign]. Clinvar id is 226497.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr10-71707066-C-T is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-0.398 with no splicing effect.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000341 (52/152360) while in subpopulation EAS AF= 0.00982 (51/5196). AF 95% confidence interval is 0.00767. There are 0 homozygotes in gnomad4. There are 32 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
