Understanding the genetic causes of cartilage tumors and vascular anomalies

Genomic-Wide Sequencing and Functional Studies to Identify the Genes Responsible for Mendelian Disorders Characterized by Cartilage Tumors and Vascular Anomalies

Observational National Institutes of Health Clinical Center (CC) · NCT06749366

This study is trying to find out the genetic reasons behind rare conditions like Ollier disease and Maffucci syndrome that cause cartilage tumors and blood vessel issues in people aged 2 and older.

What this trial studies

This observational study aims to uncover the genetic factors contributing to Ollier disease and Maffucci syndrome, which are rare disorders associated with cartilage tumors and vascular anomalies. Participants aged 2 years and older will be recruited and will undergo a series of diagnostic tests, including DXA scans, MRI, and PET scans, during a 5-day inpatient visit at the NIH Clinical Center. The study will enroll up to 100 patients over five years, with the goal of providing insights into the genetic underpinnings of these conditions. Results from the tests will be shared with participants to enhance understanding and management of their disorders.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 2 years and older diagnosed with Ollier disease or Maffucci syndrome who have cartilage tumors or vascular anomalies.

Not a fit: Patients without a diagnosis of Ollier disease or Maffucci syndrome, or those who do not have cartilage tumors or vascular anomalies, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnosis and treatment options for patients with Ollier disease and Maffucci syndrome.

How similar studies have performed: While the specific genetic causes of Ollier disease and Maffucci syndrome are not extensively studied, similar genomic sequencing approaches have shown promise in uncovering genetic factors in other rare disorders.
