dbSNP rs397517328: CDH23:c.429+4G>A (chr10-71511216-G-A) – ACMG Classification: Benign (-10 pts)

Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BA1BP4BP7

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.429+4G>A variant in CDH23 is 1.13% for South Asian chromosomes by gnomAD v2.1.1, which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen Hearing Loss Expert Panel for autosomal recessive hearing loss variants (BA1). This silent variant in CDH23 is not predicted by the computational prediction analysis using MaxEntScan to impact splicing (BP7, BP4). In summary, this variant meets criteria to be classified as benign based on the ACMG/AMP criteria applied, as specified by the Hearing Loss Expert Panel (BA1, BP7, BP4).

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]
