Blood Protein Linked to Tinnitus in Small Study
Researchers found a link between tinnitus and prestin, a protein involved in how the inner ear amplifies sound.
Tinnitus causes people to hear sounds such as ringing when no external sound is present.
The study tested 82 adults, half of whom had tinnitus, and found that those with the condition had blood levels of prestin about 50 percent higher.
Prestin has also been linked to hearing damage, but the findings do not show that it causes tinnitus.
The study was small, and tinnitus can have causes that may not involve prestin.
A separate analysis found that prestin cannot yet reliably diagnose tinnitus.
Further research may clarify the protein’s role and whether it could help develop diagnostic tests or treatments.
A small study found that adults with tinnitus had about 50 percent higher blood concentrations of the protein prestin than adults without the condition.
The study involved 82 adults, half of whom experienced tinnitus.
The findings link prestin to tinnitus but do not show that high levels of the protein cause the condition.
A diagnostic accuracy analysis found that prestin could not yet reliably diagnose tinnitus in the study sample.
Researchers said the findings offer a lead for developing diagnostic tools and potential treatments.
- Who
- Researchers studied 82 adults, half of whom experienced tinnitus. Otolaryngologist Kourosh Parham of the University of Connecticut commented on the findings.
- What
- The study found that blood concentrations of prestin were about 50 percent higher in participants with tinnitus. The results do not prove that prestin causes tinnitus.
- When
- The article was published on 2026-11-08. The study’s publication date is not stated.
- Where
- Not stated
- Why
- Researchers investigated whether prestin could be linked to tinnitus and serve as a biomarker. The study does not establish why the protein levels were higher.

What people are saying
We now have proof-of-concept that an ear protein may play a central role in the development and management of tinnitus
Our work now says there is promise in using prestin as a biomarker for tinnitus
This is our first step to developing drugs to help manage tinnitus
