Summary
Pathogenic variants in the CDH23 gene cause nonsyndromic hearing loss (NSHL) in Saudi Arabian patients. This study identifies novel CDH23 mutations, aiding in the diagnosis and genetic counseling for hearing impairment.
Area of Science:
- Genetics
- Molecular Biology
- Ophthalmology
Background:
- Mutations in the CDH23 gene are linked to nonsyndromic hearing loss (NSHL) and Usher syndrome.
- CDH23 protein is crucial for cochlear and retinal function.
