Proteus syndrome is a rare genetic disorder characterized by overgrowth of various tissues in the body. This can lead to asymmetrical growth of limbs, skin, and other organs. The condition is caused by mutations in the AKT1 gene, which affects cell growth and division. Individuals with Proteus syndrome may also experience skin abnormalities, such as tumors or lesions, and may have an increased risk of developing certain types of cancer. The severity and specific symptoms can vary widely among affected individuals, making diagnosis and management challenging.
