Proteus syndrome
is a rare condition characterized by overgrowth of the bones, skin, and other tissues. Organs and tissues affected by the disease grow out of proportion to the rest of the body. The overgrowth is asymmetric, which means it affects the right and left sides of the body differently.
Newborns with Proteus syndrome have few or no signs of the condition. Overgrowth becomes apparent between the ages of 6 and 18 months and gets more severe with age.
the pattern of overgrowth varies greatly but can affect almost any part of the body. Bones in the limbs, skull, and spine are often affected. The condition can also cause a variety of skin growths, particularly a thick, raised, and deeply grooved lesion
known as a cerebriform connective tissue nevus. This type of skin growth usually occurs on the soles of the feet and is hardly ever seen in conditions other than Proteus syndrome. Blood vessels (vascular tissue)and fat (adipose tissue) can also grow abnormally in Proteus syndrome
Proteus syndrome have neurological abnormalities, including intellectual disability, seizures, and vision loss. Affected individuals may also have distinctive facial features such as a long face, outside corners of the eyes that point downward (down-slanting palpebral fissures)
a low nasal bridge with wide nostrils, and an open-mouth expression. For reasons that are unclear, affected people with neurological symptoms are more likely to have distinctive facial features than those without neurological symptoms.
Other potential complications of Proteus syndrome include an increased risk of developing various types of noncancerous(benign)tumors and a type of blood clot called a deep venous thrombosis (DVT).DVTs occur most often in the deep veins of the legs or arms And pulmonary embolism.
Proteus syndrome is a rare condition with an incidence of less than 1 in 1 million people
results from mutation in the AKT1gene.This genetic change is not inherited from a parent;it arises randomly in one cell during the early stages of development before birth. As cells continue to grow and divide, This mixture of cells with and without genetic mutation is mosaicism
