Brief summary
International, multicenter, observational, longitudinal study to identify biomarker/s for Tuberous Sclerosis Complex and to explore the clinical robustness, specificity, and long´-term variability of these biomarker/s
Detailed description
Tuberous Sclerosis Complex (TSC) is an autosomal dominant genetic disorder characterized by the growth of numerous tumors in different body parts related to dysregulation of the mechanistic target of rapamycin (mTOR) pathway. The overall incidence of TSC is estimated to be as high as 1 in 6000 to 10,000 live birth.The main aspects of TSC that influence the quality of life are associated with the brain: seizures, evelopmental delay, intellectual disability, and autism. However, the incidence and severity of the various aspects of TSC can vary widely. TSC is generally caused by pathogenic variants in the tumor suppressor genes: TSC1 and TSC2. Confirmation of a clinical diagnosis of tuberous sclerosis is performed via TSC1 and TSC2 sequencing. There is no cure for TSC, therefore symptomatic therapy is the best possible choice, including mTOR inhibitors, vigabatrin and other antiepileptic drugs for the seizures, and neurosurgery in cases of life-threatening neurological symptoms. The aim of the study is established TSC specific biomarker/s. Such biomarkers aim to facilitate the diagnosis, treatment personalization and monitoring.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Identification of TSC biomarker/s | 36 months | All samples will be analyzed for the identification of biomarker/s via Liquid Chromatography Multiple Reaction-monitoring Mass Spectrometry (LC/MRM-MS) and compared to merged control, in order to establish the disease-specific biomarker/s. The LC/MRM-MS is performed on an ABSciex 6500 triple quadrupole mass spectrometer, coupled with a Waters Acquity UPLC. |
