Pediatric Familial Hypercholesterolaemia
Abrantes, L.B.; Alves, A.C.; Medeiros, A.M.; Correia, S.; Cruz, A.; Ferreira, A.C.; Lobarinhas, G.; Garcia, P.; Guerra, A.; Mansilha, H.; Martins, E.Familial hypercholesterolemia (FH) is an autosomal dominant disorder associated with high levels of LDL-c and premature CHD (pCHD). Identification of FH in pediatric age is essential for a timely diagnosis and management. This study aims to highlight the importance of FH diagnosis in children.
Lipid Antigen Presentation by CD1b and CD1d in Lysosomal Storage Disease Patients
Pereira, C.; Pérez-Cabezas, B.; Ribeiro, H.; Maia, M.; Cardoso, M.; Dias, A.; Azevedo, O.; Ferreira, M.; Garcia, P.; Rodrigues, E.; Castro-Chaves, P.The lysosome has a key role in the presentation of lipid antigens by CD1 molecules. While defects in lipid antigen presentation and in invariant Natural Killer T (iNKT) cell response were detected in several mouse models of lysosomal storage diseases (LSD), the impact of lysosomal engorgement in human lipid antigen presentation is poorly characterized. Here, we analyzed the capacity of monocyte-derived dendriti...

Characterization of pediatric patients from Portuguese FH study
Abrantes, LB.; Alves, A.C.; Medeiros, A.M.; Correia, S.; Cruz, A.; Lobarinhas, G.; Garcia, P.; Guerra, A.; Mansilha, H.; Martins, E.; Martins, P.The Portuguese FH Study (PFHS) started in 1999. The aim of the PFHS is to identify the cause of dyslipidemia in patients with a clinical diagnosis of FH. To date, 452 pediatric patients were referred to us, 288 of which are index patients. The aim of this study was to analyse the lipid profile and molecular diagnosis of children recruited for the PFHS.
Galactose Epimerase Deficiency: Expanding the Phenotype
Dias Costa, F.; Ferdinandusse, S.; Pinto, C.; Dias, A.; Keldermans, L.; Quelhas, D.; Matthijs, G.; Mooijer, P.; Diogo, L.; Jaeken, J.; Garcia, P.Galactose epimerase deficiency is an inborn error of metabolism due to uridine diphosphate-galactose-4'-epimerase (GALE) deficiency. We report the clinical presentation, genetic and biochemical studies in two siblings with generalized GALE deficiency.Patient 1: The first child was born with a dysmorphic syndrome. Failure to thrive was noticed during the first year. Episodes of heart failure due to dilated cardi...
Mutations in the X-linked ATP6AP2 cause a glycosylation disorder with autophagi...
Rujano, M.; Cannata Serio, M.; Panasyuk, G.; Péanne, R.; Reunert, J.; Rymen, D.; Hauser, V.; Park, J.; Freisinger, P.; Souche, E.; Guida, M.; Maier, E.The biogenesis of the multi-subunit vacuolar-type H+-ATPase (V-ATPase) is initiated in the endoplasmic reticulum with the assembly of the proton pore V0, which is controlled by a group of assembly factors. Here, we identify two hemizygous missense mutations in the extracellular domain of the accessory V-ATPase subunit ATP6AP2 (also known as the [pro]renin receptor) responsible for a glycosylation disorder with ...
Contribuição dos polimorfismos no gene FMO3 na patologia e na farmacogenética
Vilarinho, Laura Teixeira; Ferreira, F.; Almeida, L.; da Costa, C.; Janeiro, P.; Bandeira, A.; Martins, E.; Teles, E.; Garcia, P.; Azevedo, L.O Síndroma de odor a peixe ou trimetilaminúria (TMAu) é uma doença genética de transmissão autossómica recessiva que se manifesta por um forte odor corporal a peixe, devido à incapacidade de conversão do composto odorífero trimetilamina em N-óxido de trimetilamina (composto não odorífero), pela enzima flavina mono-oxigenase 3 (FMO3). Assim, os indivíduos afetados por esta patologia apresentam um odor a peixe em...
A Novel SUCLA2 Mutation in a Portuguese Child Associated With "Mild" Methylmalo...
Nogueira, Célia; Meschini, M.C.; Nesti, C.; Garcia, P.; Diogo, L.; Valongo, C.; Costa, R.; Videira, A.; Vilarinho, L.; Santorelli, F.M.Succinyl-coenzyme A synthase is a mitochondrial matrix enzyme that catalyzes the reversible synthesis of succinate and adenosine triphosphate (ATP) from succinyl-coenzyme A and adenosine diphosphate (ADP) in the tricarboxylic acid cycle. This enzyme is made up of α and β subunits encoded by SUCLG1 and SUCLA2, respectively. We present a child with severe muscular hypotonia, dystonia, failure to thrive, sensorine...
Vigilância da Gravidez na Área de Influência do Hospital de Reynaldo dos Santos
Vale, P.; Gonçalves, G.; Bastos, G.; Pastilha, P.; Luiz, P.; Paiva, M.; Garcia, P.; Berdeja, A.Efectuou-se um estudo prospectivo com base nos dados de um inquérito realizado a 350 puérperas internadas no Hospital de Reynaldo dos Santos entre Agosto e Dezembro de 1993. O objectivo foi caracterizar esta população do ponto de vista clínico e social bem como determinar a incidência de patologia no recém-nascido associada à gravidez não vigiada. Conclui-se ser elevada a incidência de gravidez não vigiada (15....
Clinical presentation and outcome in a series of 88 patients with the cblC defect
Fischer, S.; Huemer, M.; Baumgartner, M.; Deodato, F.; Ballhausen, D.; Boneh, A.; Burlina, A.B.; Cerone, R.; Garcia, P.; Gökçay, G.; Grünewald, S.The cblC defect is the most common inborn error of vitamin B12 metabolism. Despite therapeutic measures, the long-term outcome is often unsatisfactory. This retrospective multicentre study evaluates clinical, biochemical and genetic findings in 88 cblC patients. The questionnaire designed for the study evaluates clinical and biochemical features at both initial presentation and during follow up. Also the develo...
