Title

Categories:

This disease is grouped under:

PTEN hamartoma tumor syndrome

Summary Summary

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.^[1]^[2]
