Improving genetic testing for hearing loss
Optimizing Genetic Testing for Deafness for Clinical Diagnostics
This project works to make genetic test results clearer and more useful for people with inherited hearing loss.

What this research studies
The team combines detailed hearing-test patterns (audiograms) with genetic data using tools like AudioGene and OtoSCOPE to define how different genes cause hearing loss over time. They will complete gene-specific natural history studies and expand the Deafness Variation Database with physics-based protein modeling to improve variant interpretation. The project uses hierarchical surface clustering to look for genetic modifiers that change how a deafness gene affects hearing. The goal is clearer, gene-focused reports that help guide care and identify people for future gene-specific treatments.
Who could benefit from this research
Good fit: People with non-syndromic hereditary hearing loss, unexplained genetic test results, or a family history of hearing loss are the ideal candidates.
Not a fit: People whose hearing loss is clearly due to non-genetic causes (for example, noise exposure or infection) or who lack genetic testing data may not benefit directly.
Why it matters
Potential benefit: If successful, patients could receive more accurate genetic diagnoses, clearer prognoses, and better guidance for personalized care or future gene-targeted therapies.
How similar studies have performed: Previous work using AudioGene, OtoSCOPE, and the Deafness Variation Database has improved genetic interpretation, and this project builds on those successful tools.
