Leukocyte Imbalances in Mucopolysaccharidoses Patients
Lopes, Nuno; Maia, Maria L.; Pereira, Cátia S.; Mondragão-Rodrigues, Inês; Martins, Esmeralda; Ribeiro, Rosa; Gaspar, Ana; Aguiar, PatrícioMucopolysaccharidoses (MPSs) are rare inherited lysosomal storage diseases (LSDs) caused by deficient activity in one of the enzymes responsible for glycosaminoglycans lysosomal degradation. MPS II is caused by pathogenic mutations in the IDS gene, leading to deficient activity of the enzyme iduronate-2-sulfatase, which causes dermatan and heparan sulfate storage in the lysosomes. In MPS VI, there is dermatan s...
Suspecting classical homocystinuria in an adolescent born before the newborn sc...
de Carvalho, Fábia Ginja; Campos, Teresa; dos Reis, Joana Soares; Portela, Mariana; Vasconcelos, Carla; Ferreira, Carla; Cerqueira, ArnaldoIntroduction: Classical homocystinuria (HCU) is an autosomal recessive disorder caused by a deficiency in the cystathionine beta-synthase enzyme and associated with a high probability of vascular complications. Herein is presented the case of an adolescent diagnosed with HCU during cerebral venous sinus thrombosis (CVST) study. Case Report: A 14-year-old girl presented with thrombophilia screening tests suggest...

Transcriptomics profiling of Niemann-Pick type C patients: activation of the un...
Encarnação, Marisa; Coutinho, Maria Francisca; Cho, Soo-Min; Cardoso, Maria Teresa; Chaves, Paulo; Gaspar, Paulo; Santos, Juliana Inês; Ribeiro, IsauraBackground: Niemann-Pick type C (NP-C) is a neurodegenerative Lysosomal Storage Disease (LSD) with a heterogeneous clinical presentation secondary to abnormal intracellular accumulation of cholesterol. We have studied a patient with clinical diagnosis of NP-C but presenting inconclusive results regarding biomarkers testing and molecular analysis. To better characterize this patient, we have performed NGS-based ...

Encarnação, Marisa; Coutinho, Maria Francisca; Cho, Soo-Min; Cardoso, Maria Teresa; Chaves, Paulo; Ribeiro, Isaura; Santos, Juliana Inês; Gaspar, PauloNiemann-Pick type C (NP-C) is a neurodegenerative Inherited Metabolic Disease with a heterogeneous clinical presentation, due to mutations in either the NPC1 or NPC2 genes. We studied patients with clinical diagnosis of NP-C but presenting inconclusive results regarding biomarkers testing and molecular analysis. Using NGS- targeted DNA sequencing we have identified some novel putative mutations and subsequent c...
