Scientists hunt for genes behind rare bone tumor diseases

This study aims to find the genetic causes of Ollier disease and Maffucci syndrome, rare disorders that cause cartilage tumors and increase cancer risk. Researchers will study 100 people aged 2 and older using blood tests, scans, and genetic sequencing. Participants will stay at the NIH clinic for 5 days for exams and imaging. The goal is to better understand these conditions, not to test a treatment.
