Nearly 50,000 people in the United States are thought to have TSC. The prevalence is one in 6,000 births, according to the Tuberous Sclerosis Alliance.
Molecular genetic testing is available to confirm a diagnosis of TSC, to test at-risk family members or for prenatal diagnosis.
Doctors cannot predict the severity of TSC in an individual. While there is no cure, a variety of medications are used to treat symptoms. Most people with TSC live normal lifespans.
