Tuberous sclerosis complex (TSC) is an autosomal dominant syndrome that is best characterised by neurodevelopmental deficits and the presence of benign tumours (called hamartomas) in affected organs. This multi-organ disorder results from inactivating point mutations in either the TSC1 or the TSC2 genes and consequent activation of the canonical mammalian target of rapamycin complex 1 signallin...

OBJECTIVE: Neurofibromatosis type I (NF1), Tuberous sclerosis complex (TSC) and Sturge-Weber syndrome (SWS) are the most common neurocutaneous syndromes. The purpose of this study is to evaluate clinical neuroradiological manifestations patients diagnosed with NF1, TSC, SWS.MATERIAL AND METHODS: In our clinic, records 15 SWS were retrospectively reviewed between December 2017 May 2019. Clinical...

Tuberous sclerosis complex (TSC) is caused by heterozygous mutations in either the TSC1 (hamartin) or the TSC2 (tuberin) gene. Among the multisystemic manifestations of TSC, the neurodevelopmental features cause the most morbidity and mortality, presenting a considerable clinical challenge. Hamartin and tuberin form a heterodimer that inhibits the mammalian target of rapamycin complex 1 (mTORC1...

Tuberous sclerosis complex (TSC) is a genetic disorder linked to mutations of either the TSC1 or TSC2 gene, which encode proteins that form a complex to negatively regulate mammalian target of rapamycin complex 1 (mTORC1). Clinically, a small percentage of TSC patients develop severe infantile polycystic kidney disease (PKD), which is believed to be caused by deletion of the contiguous TSC2 and...

BACKGROUND Tuberous sclerosis (TSC) is a multisystem disorder encompassing a wide spectrum of pathological renal lesions. Renal involvement is commonly asymptomatic but can result in significant morbidity, and renal failure has been reported. The risk of renal failure in patients with TSC in the UK has not been defined. METHODS A survey of the 170 members of the European Dialysis and Transpla...

Autism Spectrum Disorder (ASD) is a behavioral syndrome caused by complex genetic and non-genetic risk factors. It has been proposed that these risk factors lead to alterations in the development and 'wiring' of brain circuits and hence, the emergence of ASD. Although several lines of research lend support to this theory, etiological and clinical heterogeneity, methodological issues and inconsi...

We have identified three groups of growth-constraint genes using mosaic genetic screens in Drosophila melanogaster, including PTEN (phosphatase and tensin homologue deleted on chromosome 10), and the tuberous sclerosis complex (TSC) genes, Tsc1 and Tsc2. Our studies show that all three groups of genes participate in mechanisms that regulate organ and organism size in animals. We propose that me...

INTRODUCTION Tuberous sclerosis complex (TSC) is a neurocutaneous syndrome produced by a number of genetic mutations. The disease is characterized by the development of benign tumors affecting different body systems. The most common oral manifestations of TSC are fibromas, gingival hyperplasia and enamel hypoplasia. CLINICAL CASE A 35-year-old woman diagnosed with TSC presented with a reactiv...

p34cdc2, collapsin response mediator protein 4 (CRMP4), doublecortin (DCX), HuD, and NeuN expression was assessed in tuber (n = 16) and subependymal giant cell astrocytoma (SEGA; n = 6) specimens in tuberous sclerosis complex to define the developmental phenotype and lineage of giant cells (CGs) in these lesions. Many GCs exhibited HuD and NeuN immunolabeling suggesting a differentiated neural ...
