Tuberous Sclerosis Complex
"Many individuals with TSC continue to experience uncontrolled seizures despite a cocktail of multiple antiepileptic drugs. Because new options are always needed, the TSC community welcomes clinical evaluation of new epilepsy treatments."
- Kari Luther Rosbeck, President & CEO of the Tuberous Sclerosis Alliance
Tuberous Sclerosis Complex (TSC)
CAUSE | • | Defect or mutation of TSC1 and/or TSC2 genes | |
INCIDENCE | • | ~1 in 6,000 live births1 | |
COMMON | • | Seizures, cognitive impairment, behavioral difficulties, skin/kidney/lung abnormalities, etc. | |
SYMPTOMS | |||
EPILEPSY IN TSC | • Occurs in ~80-90% of those with TSC2 | ||
• | Seizures typically begin within first year of life (infantile spasms and/or focal seizures)2 | ||
TSC is one of the most common genetic epilepsies often
exhibiting highly refractory seizures despite existing therapies
