Massive study aims to unlock secrets of rare genetic disorders
NCT ID NCT04395495
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is collecting blood, tissue, and medical information from up to 1,000 people with RASopathies—a group of genetic conditions that affect development and raise cancer risk. Researchers will store these samples and data in a database for future studies. The goal is to learn more about how these disorders work, not to test a new treatment.

Who is studied
The RASopathies are a group of developmental disorders caused by genetic changes in the genes that compose the Ras/mitogen activated protein kinase (MAPK) pathway. New RASopathies are being diagnosed frequently. This pathway is essential in the regulation of the cell cycle and the determination of cell function. Thus, appropriate function of this pathway is critical to normal development. Each syndrome in this group of disorders has unique phenotypic features, but there are many overlapping features including facial features, heart defects, cutaneous abnormalities, cognitive delays, and a predisposition to malignancies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients with a suspected or known diagnosis of any of the group of disorders known as RASopathies (e.g., Neurofibromatosis, Costello Syndrome, Noonan Syndrome). Diagnosis may be made clinically and/or confirmed through genetic testing. * Unaffected relatives of patients with a suspected or known diagnosis of any of the group of disorders known as RASopathies. Exclusion Criteria: * Individuals who do not have a suspected or definite diagnosis of a RASopathy. * Individuals who do not have a relative with a suspected or definite diagnosis of a RASopathy. * Patients who do not have the ability/capacity to undergo the informed consent process OR whose parent/legal guardian is unable to undergo the informed consent process.
