- Genetic Defects of Mitochondrial Diseases: a Next Generation Sequencing Approach: relatório finalPublication . Nogueira, Celia; Laura, VilarinhoGoal: We applied NGS to the analysis of whole mtDNA that greatly facilitates the characterization of patients suspicious of mitochondrial diseases in a timely and cost-effective fashion. Therefore, a similar strategy will be developed for nuclear encoded genes as single gene analysis of a short list of nuclear genes requires considerable time, effort and cost.
- Identification of novel L2HGDH gene mutations and update of the pathological spectrumPublication . Vilarinho, Laura; Tafulo, Sandra; Sibilio, Michelina; Kok, Fernando; Fontana, Federica; Diogo, Luisa; Venâncio, Margarida; Ferreira, Mariana; Nogueira, Celia; Valongo, Carla; Parenti, Giancarlo; Amorim, António; Azevedo, LuisaL-2-hydroxyglutaric aciduria (L-2-HGA, MIM 236792) is a neurometabolic disorder caused by the toxic accumulation of high concentration of L-2-hydroxyglutaric acid in plasma and cerebrospinal fluid. Distinct mutations on the L2HGDH gene have been associated with the clinical and biochemical phenotype. Here we present three novel mutations (Gln197X, Gly211Val and c.540+1 G4A), which increase the present deleterious collection of L2HGDH gene up to 35 mutations that we have compiled in this study. In addition, we used the haplotypic information based on polymorphic markers to demonstrate the common origin of Gly57Arg harboring chromosomes.
- Molecular Diagnosis of Mitochondrial Disease with Targeted Next Generation Sequencing: a COhoRT of 250 patientsPublication . Nogueira, Celia; Laura, Vilarinho; Cristina, Pereira; Lisbeth, Silva; Elisa, Leão Teles; Esmeralda, Rodrigues; Teresa, Campos; Esmeralda, Martins; Anabela, Bandeira; Helena, Santos; Patricia, Janeiro; Ana, GasparObjectives: The purpose of our project was to develop a NGS strategy to identify the genetic defects in 250 patients suspicious of mitochondrial disorders, to confirm the clinical and biochemical diagnosis of the disease.
- Next generation sequencing: a golden tool in mitochondrial diseasesPublication . Nogueira, Celia; Pereira, Cristina; Silva, Lisbeth; Vieira, Luis; Leão Teles, Elisa; Campos, Teresa; Rodrigues, Esmeralda; Martins, Esmeralda; Bandeira, Anabela; Soares, Gabriela; Janeiro, Patricia; Costa, Claudia; Gaspar, Ana; Santos, Helena; Vilarinho, LauraThe development of Next Generation Sequencing (NGS) has revolutionized the diagnostic approach of mitochondrial disorders, particularly in children. The purpose of our project is to develop a NGS strategy to identify the genetic defect in 250 patients, to confirm the clinical diagnosis of the disease.
