What are the symptoms? The clinical features of Proteus syndrome are overgrowth/enlargement of soft tissue and bone, which can affect any area of the body but often involving the hands and/or the feet, the skull and sometimes the whole of one side of the body (hemihypertrophy) and vascular (blood vessel) abnormalities. Epidermal naevi (superficial warty birthmarks), soft deeper (subcutaneous) lumps, thickening of the skin on the soles and bony problems, in particular, of the skull, hands/feet and curvature of the spine may also be present. The abnormalities seen in Proteus syndrome are present at birth but may become more apparent and develop with age. The clinical features described may not all be present in any one affected individual and the severity can vary widely. The nature of the varied complications of the disorder depends on the site and severity of the problem. What are the causes? The cause is genetic but the genetic defect that causes Proteus syndrome has not as yet been identified. How is it diagnosed? The diagnosis is essentially based on the presence of clinical features. As no genetic basis has been discovered no genetic tests can be undertaken. How is it treated? Treatment is symptomatic meaning that it addresses the symptoms experienced by an individual with the condition rather than addressing the cause. Medical care requires a multidisciplinary approach covering orthopaedic, dermatological (skin-based problems), genetic, surgical, dental, ophthalmological, radiological (uses of imaging such as X-rays and scans) and psychological management. Inheritance patterns and prenatal diagnosis Inheritance patternsNone. Prenatal diagnosisNone. Is there support?
