Genetic links to rotator cuff tears and muscle fatty change
The Genetic Epidemiology of Rotator Cuff Tears: The cuffGEN Study
This project looks for genetic differences that raise the risk of rotator cuff tears, lead to fatty changes in shoulder muscles, and influence outcomes after surgery or physical therapy for people with atraumatic rotator cuff tears.

What this research studies
You could help by providing medical records, shoulder imaging, and a DNA sample so researchers can compare people with and without imaging-confirmed rotator cuff tears. The team will run genome-wide scans to find genetic variants tied to tears and to fatty infiltration of rotator cuff muscles, and will study whether obesity contributes causally to those muscle changes. They will link genetic data to patient-reported outcomes from a 12-site clinical trial that randomized patients to arthroscopic surgery versus physical therapy. Findings will be used to identify genes that predict who develops more muscle damage and who benefits most from different treatments.
Who could benefit from this research
Good fit: Ideal candidates are adults with imaging-confirmed atraumatic rotator cuff tears or patients already enrolled in the ARC multi-site trial comparing arthroscopic surgery and physical therapy.
Not a fit: People without rotator cuff tears or those whose tears result from a clear acute injury are unlikely to be included or directly benefit from this work.
Why it matters
Potential benefit: If successful, this work could help predict who is at higher genetic risk for rotator cuff tears and fatty muscle change and guide more personalized choices between surgery and physical therapy.
How similar studies have performed: Family studies suggest a genetic role, but large genome-wide studies using imaging-confirmed cases and linking genetics to treatment outcomes are largely new.
