Tuberous Sclerosis Complex: Causes, Symptoms, and Treatment

What kind of doctor treats Tuberous Sclerosis Complex?
A primary care doctor often coordinates care. People usually also see specialists, including a neurologist for brain and seizure problems, a nephrologist for kidney growths, a dermatologist for skin signs, and a cardiologist for heart growths. A geneticist can help with testing and family planning.
What it is
Tuberous sclerosis complex is a rare genetic condition. It causes noncancerous growths, called tumors, to form in different organs, most often the brain, skin, kidneys, heart, and lungs. Some people have mild signs, while others have serious problems needing lifelong care.
Symptoms
Signs vary a lot from person to person. Common signs include seizures. Many people have developmental delays, meaning they learn to talk, walk, or think at a slower pace. Skin changes, such as light-colored patches, are also common.
Causes and who gets it
The condition is caused by a change in one of two genes, TSC1 or TSC2. Sometimes it is inherited from a parent; other times it happens for the first time in a child with no family history. About 1 in 6,000 babies is born with it.
How doctors diagnose it
Doctors look at a person's signs, do a physical exam, and check the skin. Imaging tests like MRI or CT scans can show growths in the brain, kidneys, or other organs. Genetic testing can often find the gene change.
Treatment
There is no cure, but treatment can manage symptoms. Medicines can help control seizures, and some newer medicines can shrink certain growths. Regular monitoring scans help doctors watch the kidneys and other organs. Surgery may be needed if a growth causes serious problems.
When to see a doctor
See a doctor if a child has seizures, developmental delays, or unusual skin patches. Anyone diagnosed should have regular checkups to monitor their organs. Get medical help right away for a seizure that does not stop, severe headache, or blood in the urine.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee. A concierge doctor usually charges more and often works alongside insurance. Either one can spend extra time coordinating this complex condition, ordering monitoring tests, and referring the patient to the right specialist.
Common questions
Can people with tuberous sclerosis complex live normal lives?
Many people with the condition live full lives, especially those with milder forms. The outlook depends on which organs are affected and how severe the problems are. Regular medical care helps many people stay well.
Will my other children have it?
If a parent has the condition, each child has a one in two chance of inheriting it. If the gene change happened for the first time in one child, the chance of it happening again is low. A genetic counselor can explain the risks for a specific family.
Are the tumors cancerous?
The growths in tuberous sclerosis complex are noncancerous. This means they do not spread the way cancer does. However, some kidney growths can cause bleeding or other problems. Doctors monitor them with regular scans.
Can it be found before birth?
Sometimes heart growths show up on a routine prenatal ultrasound, which is an imaging test done during pregnancy. This can lead to testing after birth. Not every case is found before a baby is born.
