They may also have an increased risk for developing cancer. Researchers want to learn more. Objective: To learn more about RASopathies, how genes and environmental factors contribute to cancer development in people with RASopathies, and the best way to find these cancers and other conditions early or prevent them.

Their medical records will be reviewed. Participants will give blood and urine samples. They will give a saliva or cheek cell sample. Some samples will be used for genetic testing. Participants may have a skin biopsy. Participants may have a physical exam by the RASopathies study team. They may also have exams by additional specialists, such as dentists; urologists; ear, nose, and throat doctors; and neurologists. Participants may have computed tomography of the face and mouth. They may have an ultrasound of the abdomen. They may have a bone density scan. They may have skeletal and/or spine x-rays.
