Categories:
Congenital and Genetic Diseases; Rare Cancers; Skin Diseases
This disease is grouped under:
PTEN hamartoma tumor syndrome

Summary Summary


Listen
Proteus-like syndrome describes people who do not meet the diagnostic criteria for Proteus syndrome but who share many of the characteristic signs and symptoms associated with the condition. Affected people may experience some of the following features: overgrowth of the bones, skin, and other tissues; hamartomas; abnormalities of the skin, blood vessels (vascular tissue) and fat (adipose tissue); and distinctive facial features. Approximately 50% of people with Proteus-like syndrome are found to have changes (mutations) in the PTEN gene. In these cases, the inheritance is autosomal dominant. Treatment is based on the signs and symptoms present in each person.[9723][1]

Symptoms Symptoms


Listen

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
