Proteus Syndrome

This study will examine rare congenital disorders that involve malformations and abnormal growth. It will focus on patients with Proteus syndrome, whose physical features are characterized by overgrowth, benign tumors of fatty tissue or blood vessels, asymmetric arms or legs, and large feet with very thick soles. The study will explore the genetic and biochemical cause and course of the disease, the changes in symptoms over time, and the effects of the disease on patients. Patients with Proteus syndrome may be eligible for this study. Study candidates will have a medical history and physical examination, including X-rays and possibly other imaging tests, such as computerized tomography (CT), magnetic resonance imaging (MRI) and ultrasound. Other tests and examinations may be done if needed. Those enrolled in the study may be interviewed or complete questionnaires, or both, about how their disease affects them. Patients will provide a small blood sample for research....
