In fact, CDH23 mutations accounted for 9.4% (3/32)—or possibly up to 12.5% (4/32)—of postlingual adult-onset SNHL, while the genetic load of CDH23 mutations was 3.1% (4/128) in our pediatric cohort with prelingual-onset severe-to-profound SNHL [9]. This evidence concerns the gene CDH23 and sensorineural hearing loss disorder.
