Progression of multisystem proteinopathy type 1 (MSP1)

Natural history of multisystem proteinopathy-1

NIH-funded research University of Miami School of Medicine · NIH-11171889

This project will track motor and other symptoms over time in adults with MSP1 caused by VCP gene variants to find reliable ways to measure change.

What this research studies

You and other adults with MSP1 caused by a VCP missense variant will be followed at multiple centers with regular clinic visits and testing. The team will use the North Star Assessment for limb-girdle–type dystrophies (NSAD) and other clinical outcome measures to see how well they capture real changes in motor function. Researchers will document when different MSP1 features appear, how quickly they progress, and how factors like age or symptom mix affect outcomes. The study aims to define expected disease trajectories and set thresholds for what counts as a meaningful change for future trials.

Who could benefit from this research

Good fit: Adults (age 21 and over) who carry a pathogenic missense variant in the VCP gene and show clinical signs of MSP1 are the ideal candidates.

Not a fit: People without VCP-related MSP1, children under 21, or those with other forms of ALS are unlikely to directly benefit from this specific natural-history effort.

Why it matters

Potential benefit: If successful, this work could improve how clinical trials are designed and speed development of treatments targeting VCP-related MSP1.

How similar studies have performed: Motor outcome scales like the NSAD have been useful in other neuromuscular disorders and preclinical VCP-targeting therapies showed promise, but large natural-history datasets for MSP1 remain limited.
