Genetics and epigenetics of otosclerosis

The genomic and epigenomic landscape of otosclerosis

NIH-funded research University of Arizona · NIH-11301883

This project looks for genetic and epigenetic changes that cause otosclerosis to help explain and someday reduce hearing loss in adults.

What this research studies

If you have otosclerosis or a family history, researchers will use DNA and other samples from many affected people and families to find gene changes and epigenetic marks linked to the condition. They will apply modern genomic sequencing and epigenomic profiling techniques to compare affected and unaffected individuals. The team is working with a large, already-collected cohort that lets them search for inherited and new mutations as well as age-related epigenetic patterns. Findings could point to biological pathways that explain why the otic capsule bone remodels abnormally in otosclerosis.

Who could benefit from this research

Good fit: Ideal participants are adults with a clinical diagnosis of otosclerosis—especially those with bilateral disease or a family history—who can provide DNA, medical records, or hearing test results.

Not a fit: People without otosclerosis or whose hearing loss is due to unrelated causes are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could improve diagnosis and point to new targets for therapies to prevent or slow hearing loss from otosclerosis.

How similar studies have performed: Previous genetic work has identified some candidate genes and links to other bone disorders, but the epigenetic approach in otosclerosis is relatively new and less tested.
