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]

Variant classified as Uncertain Significance - Favor Benign. The Val154Met varia nt has not been reported in the literature nor previously identified by our labo ratory. This residue is conserved across species; however, computational analyse s (PolyPhen, SIFT, AlignGVGD) provide inconsistent predictions regarding the imp act to the protein and this information is not very predictive of pathogenicity anyway. In summary, the clinical significance of this variant cannot be determin ed with certainty at this time. -

The c.460G>A (p.V154M) alteration is located in exon 7 (coding exon 6) of the CDH23 gene. This alteration results from a G to A substitution at nucleotide position 460, causing the valine (V) at amino acid position 154 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
