Genotype-phenotype correlations and BH4 estimated responsiveness in patients wi...
Vieira Neto, Eduardo; Laranjeira, F.; Quelhas, D.; Ribeiro, I.; Seabra, A.; Mineiro, N.; Carvalho, L.; Lacerda, L.; Ribeiro, M.Background: Genetic heterogeneity and compound heterozygosis give rise to a continuous spectrum of phenylalanine hydroxylase deficiency and metabolic phenotypes in phenylketonuria (PKU). The most used parameters for evaluating phenotype in PKU are pretreatment phenylalanine (Phe) levels, tolerance for dietary Phe, and Phe overloading test. Phenotype can vary from a "classic" (severe) form to mild hyperphenylala...
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 ...

MAN1B1 Deficiency: An Unexpected CDG-II
Rymen, D.; Peanne, R.; Millón, M.; Race, V.; Sturiale, L.; Garozzo, D.; Mills, P.; Clayton, P.; Asteggiano, C.; Quelhas, D.; Cansu, A.; Martins, E.Congenital disorders of glycosylation (CDG) are a group of rare metabolic diseases, due to impaired protein and lipid glycosylation. In the present study, exome sequencing was used to identify MAN1B1 as the culprit gene in an unsolved CDG-II patient. Subsequently, 6 additional cases with MAN1B1-CDG were found. All individuals presented slight facial dysmorphism, psychomotor retardation and truncal obesity. Gene...
Clinical, biochemical and molecular characterization of cystinuria in a cohort ...
Barbosa, M.; Lopes, A.; Mota, C.; Martins, E.; Oliveira, J.; Alves, S.; De Bonis, P.; Mota, M. do C.; Dias, Carlos Matias; Rodrigues-Santos, P.Cystinuria is a rare autosomal inherited disorder characterized by impaired transport of cystine and dibasic aminoacids in the proximal renal tubule. Classically, Cystinuria is classified as type I (silent heterozygotes) and non-type I (heterozygotes with urinary hyperexcretion of cystine). Molecularly, Cystinuria is classified as type A (mutations on SLC3A1 gene) and type B (mutations on SLC7A9 gene). The goal...
