Leukocyte Imbalances in Mucopolysaccharidoses Patients
Lopes, Nuno; Maia, Maria L.; Pereira, Cátia S.; Mondragão-Rodrigues, Inês; Martins, Esmeralda; Ribeiro, Rosa; Gaspar, Ana; Aguiar, Patrício(This article belongs to the Special Issue Inherited Metabolic Disorders: From Bench to Bedside); Mucopolysaccharidoses (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, ...
Exosomal microRNAs as possible biomarkers for a rare disease affecting lipids
Encarnação, Marisa; David, Hugo; Ribeiro, Isaura; Vieira, Luís; Carneiro Silva, Catarina; Martins, Esmeralda; Cardoso, Maria TeresaExosomes mediate the communication between cells and the characterization of their content can provide important insights into health and disease. Their cargo includes proteins, lipids and nucleic acids (including microRNAs (miRNAs)). miRNAs regulate many cellular processes, including metabolism. (...); This work received financial support from PT national funds (FCT/MCTES, Fundação para a Ciência e Tecnologia ...
Congenital disorders of glycosylation
Mendes, Ana Raquel; Quelhas, D; Correia, Joana; Paiva Coelho, Margarida; Bandeira, Anabela; Martins, EsmeraldaCongenital disorders of glycosylation are a highly variable, rapidly expanding family of genetic diseases that result from defects in the synthesis of glycans. The vast majority of these monogenic diseases are inherited in an autosomal recessive way, but some types follow an autosomal dominant or X-linked inheritance. The present work aimed to review the state of the art of congenital disorders of glycosylation...

Utility of Gene Panels for the Diagnosis of Inborn Errors of Metabolism in a Me...
Barbosa-Gouveia, Sofia; Vázquez-Mosquera, María E.; González-Vioque, Emiliano; Álvarez, José V.; Chans, Roi; Laranjeira, Francisco; Martins, EsmeraldaNext-generation sequencing (NGS) technologies have been proposed as a first-line test for the diagnosis of inborn errors of metabolism (IEM), a group of genetically heterogeneous disorders with overlapping or nonspecific phenotypes. Over a 3-year period, we prospectively analyzed 311 pediatric patients with a suspected IEM using four targeted gene panels. The rate of positive diagnosis was 61.86% for intermedia...
Continuous use of glycomacropeptide in the nutritional management of patients w...
Pena, Maria João; Pinto, Alex; de Almeida, Manuela Ferreira; de Sousa Barbosa, Catarina; Ramos, Paula Cristina; Rocha, Sara; Guimas, ArlindoBackground: In phenylketonuria (PKU), modified casein glycomacropeptide supplements (CGMP-AA) are used as an alternative to the traditional phenylalanine (Phe)-free L-amino acid supplements (L-AA). However, studies focusing on the long-term nutritional status of CGMP-AA are lacking. This retrospective study evaluated the long-term impact of CGMP-AA over a mean of 29 months in 11 patients with a mean age at CGMP...
SLC35A2-CDG: Novel variant and review
Quelhas, D; Correia, Joana; Jaeken, Jaak; Azevedo, Luísa; Lopes-Marques, Mónica; Bandeira, Anabela; Keldermans, Liesbeth; Matthijs, GertSLC35A2 encodes the X-linked transporter that carries uridine diphosphate (UDP)-galactose from the cytosol to the lumen of the Golgi apparatus and the endoplasmic reticulum. Pathogenic variants have been associated to a congenital disorder of glycosylation (CDG) with epileptic encephalopathy as a predominant feature. Among the sixty five patients described so far, a strong gender bias is observed as only seven ...
The 2020S tooth fairy: from loose tooth to neuronal cell cultures, a method to ...
Coutinho, Maria Francisca; Santos, Juliana Inês; Matos, Liliana; Teles, Elisa Leão; Martins, Esmeralda; Matos, Paula Garcia; Janeiro, PatríciaLysosomal storage disorders (LSD) are a group of rare diseases caused mutations in genes that encode lysosomal enzymes, membrane proteins or transporters. This leads to an accumulation of undegraded substrates, which ultimately causes a broad range of highly debilitating clinical symptoms affecting multiple organs/systems, including the central nervous system. Yet, most therapies for LSD are limited to treating...

Familial chylomicronemia syndrome in Portugal
Alves, Ana Catarina; Miranda, Beatriz; Sequeira, Sílvia; Moldovan, Oana; Nunes, Catarina; Antunes, Henedina; Martins, Esmeralda; Gonçalves, RuteFamilial chylomicronemia syndrome (FCS) is a rare autosomal recessive disorder of lipoprotein metabolism. It is characterized by marked elevation of triglyceride and chylomicron levels, lipaemic plasma, recurrent pancreatitis, eruptive xanthoma, hepatosplenomegaly, andliapemiaretinalis. All genes associated with FCS (LPL, APOC2, APOA5, LMF1 and GPHBP1) have an effect on the activity of lipoprotein lipase (LPL)....
