Unusually mild tuberous sclerosis phenotype is associated with TSC2 R905Q mutationAn C Jansen
Neurogenetics Unit, Montreal Neurological Hospital and Institute, McGill University, Montreal, Quebec, Canada
Ann Neurol 60:528-39. 2006..These findings have implications for the large number of patients with limited clinical features of TSC and for genetic counseling in these families...
A reliable cell-based assay for testing unclassified TSC2 gene variantsRicardo Coevoets
Department of Clinical Genetics, Erasmus Medical Centre, Rotterdam, The Netherlands
Eur J Hum Genet 17:301-10. 2009..In 12 cases, we concluded that the identified variant was pathogenic. The ICW is a rapid, reproducible assay, which can be applied to the characterisation of the effects of novel TSC2 variants on the activity of the TSC1-TSC2 complex...
TSC2 missense mutations inhibit tuberin phosphorylation and prevent formation of the tuberin-hamartin complexM Nellist
Department of Clinical Genetics, Erasmus University, 3015 GE Rotterdam, The Netherlands
Hum Mol Genet 10:2889-98. 2001..Although mutations that prevent tuberin tyrosine phosphorylation also inhibit tuberin-hamartin binding and the chaperone function, our results indicate that only hamartin is phosphorylated in the tuberin-hamartin complex...
Identification and characterization of the interaction between tuberin and 14-3-3zetaMark Nellist
Department of Clinical Genetics, Erasmus Medisch Centrum, Dr Molewaterplein 50, 3015 GE Rotterdam, The Netherlands
J Biol Chem 277:39417-24. 2002..Finally, it was shown that the tuberin/14-3-3zeta interaction is regulated by Akt-mediated phosphorylation of tuberin, providing insight into how tuberin may regulate phosphorylation of S6...
Analysis of TSC1 truncations defines regions involved in TSC1 stability, aggregation and interactionMarianne Hoogeveen-Westerveld
Department of Clinical Genetics, Erasmus Medical Centre, Dr Molewaterplein 50, 3015 GE Rotterdam, The Netherlands
Biochim Biophys Acta 1802:774-81. 2010..Here we investigate TSC1 structure and function by analysing a series of truncated TSC1 proteins. We identify specific regions of the protein that are important for TSC1 stability, localisation, interactions and function...
Functional assessment of variants in the TSC1 and TSC2 genes identified in individuals with Tuberous Sclerosis ComplexMarianne Hoogeveen-Westerveld
Department of Clinical Genetics, Erasmus Medical Centre, Rotterdam, The Netherlands
Hum Mutat 32:424-35. 2011..In addition we identified eight putative splice site mutations (five TSC1 and three TSC2). The remaining 24 TSC1 and 34 TSC2 variants were classified as probably neutral...
Identification of a region required for TSC1 stability by functional analysis of TSC1 missense mutations found in individuals with tuberous sclerosis complexMelika Mozaffari
Department of Clinical Genetics, Erasmus Medical Centre, Rotterdam, The Netherlands
BMC Med Genet 10:88. 2009..Recently it has been shown that missense mutations to the TSC1 gene can cause TSC...
Missense mutations to the TSC1 gene cause tuberous sclerosis complexMark Nellist
Department of Clinical Genetics, Erasmus Medical Centre, Rotterdam, The Netherlands
Eur J Hum Genet 17:319-28. 2009..We show that specific amino-acid substitutions close to the N-terminal of TSC1 reduce steady-state levels of TSC1, resulting in the activation of mTOR signalling and leading to the symptoms of TSC...
Functional characterisation of the TSC1-TSC2 complex to assess multiple TSC2 variants identified in single families affected by tuberous sclerosis complexMark Nellist
Department of Clinical Genetics, Erasmus Medical Centre, Rotterdam, The Netherlands
BMC Med Genet 9:10. 2008..3. The TSC1 and TSC2 gene products, TSC1 and TSC2, interact to form a protein complex that inhibits signal transduction to the downstream effectors of the mammalian target of rapamycin (mTOR)...
Distinct effects of single amino-acid changes to tuberin on the function of the tuberin-hamartin complexMark Nellist
Department of Clinical Genetics, Erasmus MC, 3015 GE Rotterdam, The Netherlands
Eur J Hum Genet 13:59-68. 2005..Here, we investigate how these mutations affect the role of tuberin in the control of signal transduction through mTOR. Our data indicate that specific amino-acid substitutions have distinct effects on tuberin function...
Functional assessment of TSC1 missense variants identified in individuals with tuberous sclerosis complexMarianne Hoogeveen-Westerveld
Department of Clinical Genetics, Erasmus Medical Centre, 3015 GE Rotterdam, The Netherlands
Hum Mutat 33:476-9. 2012..Our new data confirm our previous finding that the N-terminal region of TSC1 is essential for TSC1 function...
Phosphorylation and binding partner analysis of the TSC1-TSC2 complexMark Nellist
Department of Clinical Genetics, Erasmus Medisch Centrum, Dr Molewaterplein 50, 3015 GE Rotterdam, The Netherlands
Biochem Biophys Res Commun 333:818-26. 2005..In addition, we identified three TSC1-TSC2 interacting proteins, including DOCK7 a putative rhebGEF...
Mutational analysis of the TSC1 and TSC2 genes in a diagnostic setting: genotype--phenotype correlations and comparison of diagnostic DNA techniques in Tuberous Sclerosis ComplexOzgur Sancak
Department of Clinical Genetics, Erasmus Medical Center, Rotterdam, The Netherlands
Eur J Hum Genet 13:731-41. 2005..Interestingly, consistent with other studies, the phenotypes of the patients in which no mutation was identified were, overall, less severe than those of patients with either a known TSC1 or TSC2 mutation...
Functional assessment of TSC2 variants identified in individuals with tuberous sclerosis complexMarianne Hoogeveen-Westerveld
Department of Clinical Genetics, Erasmus Medical Centre, Rotterdam, The Netherlands
Hum Mutat 34:167-75. 2013..Our data support the notion that different, nonterminating TSC2 mutations can have distinct effects on TSC1-TSC2 function, and therefore, on TSC pathology...
The TSC1-TSC2 complex consists of multiple TSC1 and TSC2 subunitsMarianne Hoogeveen-Westerveld
Department of Clinical Genetics, Erasmus Medical Centre, Dr, Molewaterplein 50, Rotterdam, 3015 GE, The Netherlands
BMC Biochem 13:18. 2012..Here we investigate the quaternary structure of the TSC1-TSC2 complex by gel filtration and coimmunoprecipitation...
