Phenylketonuria in Portugal: Genotype–Phenotype Correlations Using Molecular, B...
Ferreira, F; Azevedo, L; Neiva, R; Sousa, C; Fonseca, H; Marcão, A; Rocha, H; Carmona, C; Ramos, S; Bandeira, A; Martins, E; Campos, T; Rodrigues, EBackground: The impairment of the hepatic enzyme phenylalanine hydroxylase (PAH) causes elevation of phenylalanine levels in blood and other body fluids resulting in the most common inborn error of amino acid metabolism (phenylketonuria). Persistently high levels of phenylalanine lead to irreversible damage to the nervous system. Therefore, early diagnosis of the affected individuals is important, as it can pre...

Cruz, S; Taipa, R; Nogueira, C; Pereira, C; Almeida, S; Neiva, R; Geraldes, T; Guimarães, A; Melo-Pires, M; Vilarinho, LINTRODUCTION: Mitochondrial disorders display remarkable genetic and phenotypic heterogeneity. METHODS: We performed a retrospective analysis of the clinical, histological, biochemical, and genetic features of 65 patients with molecular diagnoses of mitochondrial disorders. RESULTS: The most common genetic diagnosis was a single large-scale mitochondrial DNA (mtDNA) deletion (41.5%), and the most frequent clini...
