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]

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 17 uncertain in NM_022124.6

BP4

Computational evidence support a benign effect (MetaRNN=0.013924986).

BP6

Variant 10-71705031-G-A is Benign according to our data. Variant chr10-71705031-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 448998.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.000136 (198/1460418) while in subpopulation AMR AF = 0.00282 (126/44714). AF 95% confidence interval is 0.00242. There are 0 homozygotes in GnomAdExome4. There are 97 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
