It develops with a pathogenic mutation in tumour suppressor genes i.e. Tuberous Sclerosis Complex 1 or Tuberous Sclerosis Complex 2 which codes for protein hamartin and tuberin leading to unopposed hyperactivation of the mammalian target of the rapamycin signalling pathway. It presents with a triad of facial angiofibroma, intellectual disability, and epilepsy. We present a case of a 17-month female toddler with abnormal body movement with loss of consciousness and later developing into generalised jerky movements. On magnetic resonance imaging, a diagnosis of tuberous sclerosis was made. The patient underwent symptomatic management with anti-epileptic. As seizures in these cases are subtle, they remain undiagnosed for a long time leading to delays in management and developing refractory seizures.en-USAngiofibromaCase reportsSeizuresTuberous sclerosisTumor suppressor geneArticle
