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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.55).
BP6
Variant 10-71793417-G-C is Benign according to our data. Variant chr10-71793417-G-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 46011.We mark this variant Likely_benign, oryginal submission is: [Conflicting_classifications_of_pathogenicity].
BP7
Synonymous conserved (PhyloP=-0.078 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.0000267 (39/1461702) while in subpopulation AFR AF = 0.00108 (36/33480). AF 95% confidence interval is 0.000798. There are 1 homozygotes in GnomAdExome4. There are 21 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
