What causes the Proteus syndrome?
Proteus syndrome results from a mutation in the AKT1 gene. 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, some cells will have the mutation and other cells will not.

How many cases of Proteus syndrome are there?

Does Proteus syndrome hurt?
One of the features of Proteus syndrome the researchers looked at was the cerebriform connective tissue nevus (CCTN), which is a disfiguring, massive overgrowth of the skin, typically on the soles of the feet. These lesions can cause patients pain and make it difficult to walk and find shoes that fit.
What is the life expectancy of someone with Proteus syndrome?
The prognosis of this condition is poor as the mortality rate for those affected is high. It has been noted that about a median survival age for the affected is only 2.5 days. It’s considered a lucky case if the affected child has survived at least 6 months of life and more luckier if they have reached their teens.
What are the symptoms of Proteus syndrome?
Noncancerous (benign) tumors
What is Proteus syndrome also known as Wiedemann syndrome?
Proteus syndrome, also known as Wiedemann’s syndrome (named after the German paediatrician Hans-Rudolf Wiedemann), is a congenital disorder that causes skin overgrowth and atypical bone development, often accompanied by tumors over half the body.
What does Proteus syndrome mean?
Proteus syndrome is a rare congenital, multisystemic, hamartomatous condition characterised by asymmetrical overgrowth of almost any part of the body and a broad spectrum of manifestations. It can affect tissue from any germinal layer.
