Tuberous sclerosis (TWO-bur-uhs skluh-ROH-sis), also called tuberous sclerosis complex, is a rare genetic disease that causes noncancerous (benign) tumors to grow in many parts of the body. The signs and symptoms of tuberous sclerosis vary widely, depending on where the tumors develop and how severely a person is affected.
Tuberous sclerosis is often detected during infancy or childhood. Some people with tuberous sclerosis have such mild signs and symptoms that the condition isn't diagnosed until adulthood, or it goes undiagnosed. Others experience serious disabilities.
Although there's no cure for tuberous sclerosis, treatments are being studied. The course or severity of the disease can't be predicted, but with appropriate care, many people who have tuberous sclerosis lead full, productive lives.
