Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients with a suspected or confirmed diagnosis of any RASopathy, as well as their unaffected relatives.
✕Probably not a fit
Patients without a suspected or confirmed diagnosis of a RASopathy or those without affected relatives may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study aims to collect and store bio-specimens from patients diagnosed with or suspected to have RASopathies, a group of genetic disorders affecting the Ras/MAPK pathway. The study will gather various biological samples, including blood, tissue, and other bodily fluids, to investigate the metabolic and molecular basis of these conditions. Additionally, demographic and medical history data will be collected to create a comprehensive longitudinal database for future research. The goal is to better understand the commonalities and differences among these rare disorders.
Why it matters
Potential benefit: If successful, this study could enhance the understanding of RASopathies and lead to improved diagnostic and therapeutic strategies for affected patients.
How similar studies have gone: While this approach is focused on a specific group of rare disorders, similar studies have shown promise in understanding genetic conditions through biorepositories.

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.
