Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP4_ModerateBS1BS2

The NM_022124.6(CDH23):c.385G>A(p.Ala129Thr) variant causes a missense change. The variant allele was found at a frequency of 0.000535 in 1,613,624 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A129V) has been classified as Uncertain significance. The gene CDH23 is included in the ClinGen Criteria Specification Registry.

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

Specifications for CDH23 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.095492005).

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000562 (822/1461364) while in subpopulation NFE AF = 0.000668 (743/1111638). AF 95% confidence interval is 0.000629. There are 2 homozygotes in GnomAdExome4. There are 404 alleles in the male GnomAdExome4 subpopulation. Median coverage is 40. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR,Unknown gene
