What is Tuberous Sclerosis Complex?

 

What is Tuberous Sclerosis Complex?

TSC is a rare genetic disorder that causes non-cancerous tumors to grow in different parts of the body, especially the:

  • Brain

  • Skin

  • Kidneys

  • Heart

  • Eyes

  • Lungs


🧬 Cause:

  • Caused by mutations in the TSC1 or TSC2 genes.

  • These genes regulate cell growth. When they are mutated, cells grow uncontrollably, forming tumors.


🧒🏻 TSC in Children – Key Symptoms:

  • Seizures (common and often early sign)

  • Developmental delay or intellectual disability

  • Autism spectrum disorder

  • Skin findings:

    • Hypomelanotic macules (white patches)

    • Facial angiofibromas

    • Shagreen patches

  • Behavioral issues

  • Kidney cysts or tumors (angiomyolipomas)


🩺 Diagnosis:

  • Clinical exam + imaging (MRI, CT)

  • Genetic testing (TSC1/TSC2 mutations)

  • EEG for seizure monitoring


💊 Treatment:

  • No cure, but symptoms can be managed:

    • Anti-seizure medications

    • Behavioral therapy / educational support

    • mTOR inhibitors (like everolimus) to shrink tumors

    • Regular screening for organs
