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: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.032257378).

BP6

Variant 10-71645960-G-A is Benign according to our data. Variant chr10-71645960-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1006937.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000722 (11/152350) while in subpopulation SAS AF = 0.00186 (9/4832). AF 95% confidence interval is 0.000971. There are 1 homozygotes in GnomAd4. There are 7 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
