Background: Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder characterized by mutations in the TSC1 and TSC2 genes, leading to the dysregulation of the mammalian target of rapamycin (mTOR) pathway. This dysregulation results in the development of benign tumors across multiple organ systems and poses significant neurodevelopmental challenges. The clinical manifestations of TSC vary widely and include subependymal giant cell astrocytomas (SEGAs), renal angiomyolipomas (AMLs), facial angiofibromas (FAs), and neuropsychiatric conditions such as autism spectrum disorder (ASD).

Article Synopsis
  • Pseudohypoparathyroidism (PHP) is a rare disorder causing symptoms like convulsions and involuntary movements due to resistance to parathyroid hormone, resulting in low calcium levels.
  • A case study of a 7-year-old girl showed her involuntary movements were initially misdiagnosed and treated with carbamazepine but led to convulsions and revealed significant underlying electrolyte imbalances and brain calcifications.
  • Diagnosis was confirmed via genetic testing, and treatment with calcium and vitamin D resolved her symptoms, highlighting the importance of early blood tests for proper PHP diagnosis in patients with similar movement disorders.
