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. This research study proposes to collect and store human bio-specimens from patients with suspected or diagnosed RASopathies. Once obtained, blood and/or tissue samples will be processed for: metabolic function studies, biomarkers, genetic studies, and/or the establishment of immortalized cell lines. In addition, data from the medical record (including neuropsychological evaluations) and surveys will be stored to create a longitudinal database for research conducted at CCHMC or at other research institutions.
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.
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.

Trial groupsSee each trial group below.
Collection of biospecimen
Collect specimens derived from blood, buccal cells, sputum, urine, bone marrow, tumor tissue and residual specimens, including but not limited to pleural fluid, ascetic fluid, chyle, skin, lung, lymphatic or renal tissue and/or bronchoalveolar lavage fluid, tissue specimens, and/or cells that are left over from clinical procedures from enrolled patients for research purposes only.
Collection of medical history
Collect demographic information, medical history, and clinical test results to create a longitudinal research database of participants with suspected or diagnosed RASopathies. Participants will also complete surveys to be included in the research database (see "Research Database" section for details).
Release of Specimens and Clinical Data to Other Investigators for use in RASopathy Research
Release of fresh or frozen specimens and clinical data to both CCHMC and external investigators. Applications for use of bio-specimen and/or data must be approved by the Repository Use Committee through the completion of a specimen request form. Among other data, the specimen request form will require information concerning: Principal Investigator, funding sources, a research synopsis, Institutional Review Board (IRB) approval of the research project, and details about the required samples. At the time a de-identified sample is requested, the requesting investigator may also request de-identified clinical data if needed.
