Summary
Genetic factors significantly contribute to non-syndromic hearing loss (NSHL). Advances in genetic testing and counseling aid in early detection and intervention for NSHL, improving clinical outcomes.
Area of Science:
- Genetics
- Otolaryngology
- Medical Diagnostics
Background:
- Non-syndromic hearing loss (NSHL) is frequently caused by genetic factors.
- Molecular techniques have advanced genetic diagnosis and counseling for NSHL.
- Newborn hearing screening enables early detection, while genetic screening identifies causes.
Purpose of the Study:
- To provide a comprehensive reference for NSHL genetic counseling and testing.
- To summarize current knowledge on NSHL incidence, genetics, and clinical aspects.
- To guide professionals in genetic testing, data interpretation, and risk assessment.
Main Methods:
- Review and synthesis of existing literature on NSHL.
- Summarization of data on genetic factors, inheritance, and pathogenesis.
- Analysis of clinical manifestations, genotype-phenotype correlations, and testing strategies.
Main Results:
- 110 pathogenic genes for NSHL have been identified.
- Challenges remain in clinical identification and data interpretation.
- Genetic counseling and prenatal diagnosis require robust genetic testing.
Conclusions:
- Genetic diagnosis and counseling are crucial for early intervention in NSHL.
- Continued research is needed to address challenges in clinical identification.
- This guideline serves as a reference for managing NSHL through genetic approaches.
