BACKGROUND Tuberous sclerosis complex (TSC) is a rare autosomal dominant genetic disorder. Many gaps remain in the understanding of TSC because of the complexity in clinical presentation. The TuberOus SClerosis registry to increase disease Awareness (TOSCA) is an international disease registry designed to address knowledge gaps in the natural history and management of TSC. Here, we present the ...
Tuberous sclerosis complex (TSC) is a neurocutaneous autosomal dominant disorder that results from mutations within either the TSC1 gene or the TSC2 gene. Diagnosis is based on well-established clinical criteria or genetic criteria. Clinical features are highly variable and could be developing over the life. We present a case of TSC with a molecular test that identified a novel variant in TSC2 ...
Multifocal micronodular pneumocyte hyperplasia (MMPH) is rare entity seen mostly in patients with the tuberous sclerosis complex (TSC). We present the case of a 50 year old woman with TSC (confirmed TSC2 mutation) found to have multiple ground glass opacities with an upper lobe predominance on a screening chest CT. No abnormalities were detected in other viscera. A thoracoscopic lung biopsy obt...

Background: Tuberous Sclerosis Complex (TSC) is a genetic disease that affects multiple body systems with the neurological manifestations causing greatest burden. The objective of this study was to understand scope TSC care delivery across Canada. Methods: A survey developed after literature review and discussion amongst two Paediatric Epileptologists one Nurse Practitioner expertise in TSC. Ca...
Tuberous sclerosis complex (TSC) is caused by a mutation in the TSC1 or TSC2 genes. However, 15% of patients have no mutation identified. Tubers and subependymal nodules (SENs) are the typical brain lesions in TSC and are present in 90-95% of patients. The objective of this study is to characterize the specific genotype-phenotype of patients without these lesions. We analyzed the features of 11...
Epilepsy associated with tuberous sclerosis complex (TSC) is characterized by early onset and intractable seizures in the majority of children. There is a solid evidence of clinical efficacy of vigabatrin in interrupting infantile spasms associated with TSC. Due to an early diagnosis we were able to start vigabatrin at the very early onset of seizures in 10 children, who subsequently underwent ...
Increased mTORC1 signaling from TSC1/TSC2 inactivation is found in cancer and causes tuberous sclerosis complex (TSC). The role of mesenchymal-derived cells in TSC tumorigenesis was investigated through disruption of Tsc2 in craniofacial and limb bud mesenchymal progenitors. Tsc2cKOPrrx1-cre mice had shortened lifespans and extensive hamartomas containing abnormal tortuous, dilated vessels prom...
Tuberous sclerosis complex (TSC) is an autosomal dominant disorder that results from mutations in the TSC1 or TSC2 genes and is associated with hamartoma formation in multiple organ systems. The neurological manifestations of TSC are particularly challenging and include infantile spasms, intractable epilepsy, cognitive disabilities, and autism. Progress over the past 15 years has demonstrated t...
TSC2 modulates actin cytoskeleton and focal adhesion through TSC1-binding domain and the Rac1 GTPase
Tuberous sclerosis complex (TSC) 1 and TSC2 are thought to be involved in protein translational regulation and cell growth, and loss of their function is a cause of TSC and lymphangioleiomyomatosis (LAM). However, TSC1 also activates Rho and regulates cell adhesion. We found that TSC2 modulates actin dynamics and cell adhesion and the TSC1-binding domain (TSC2-HBD) is essential for this functio...
