Summary

This study aims to understand the genetic and biological causes of Proteus syndrome, a rare condition causing abnormal growth of bones, skin, and other tissues. Researchers will follow up to 1,500 participants over time, using medical exams, imaging, and blood tests to track how the disease changes. The goal is to better diagnose and characterize the disorder, not to test a new treatment.
