Study of Proteus Syndrome and Related Congenital Disorders
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 and their parents may be eligible for this study. Parents will be studied, when possible, for comparison of molecular findings. 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 will have will be interviewed or complete questionnaires, or both, about how their disease affects them. (Parents will be asked about their feelings about having a child with a rare disorder.) Patients will provide a small blood sample for research and may be asked to undergo biopsies from a normal area of skin and from a tumor.
