Living with Tuberous sclerosis syndrome

A genetic condition with noncancerous growths in the brain, kidneys, heart, skin, and other organs, and developmental differences.

Understanding Tuberous sclerosis syndrome

Tuberous sclerosis complex is a genetic condition that causes many noncancerous (benign) tumors to grow in different parts of the body.

Growths can occur in the brain, kidneys, heart, eyes, lungs, skin, and other organs. It often affects the brain and can bring seizures, intellectual disability, ADHD, autism spectrum disorder, and behavior or mood differences. Nearly everyone has skin changes. Signs and symptoms vary from person to person and can appear at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Growths in the brain (cortical tubers)
  • Seizures, including infantile spasms
  • Autism and behavior differences
  • Patches of lighter skin and skin growths (angiofibromas)
  • Kidney growths and kidney problems
  • Heart growths (cardiac rhabdomyoma)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists, cancer specialists, genetic specialists and kidney specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    TSC Alliance and Epilepsy Foundation may keep lists of experts for this condition.

InheritanceAutosomal Dominant

GARD says changes in genes (variants) cause this condition and that it is autosomal dominant, so one changed copy of a gene can be enough. It doesn't name a specific gene here.
