Unraveling the effect of silent, intronic and missense mutations on VWF splicin...
Borràs, N; Orriols, G; Batlle, J; Pérez-Rodríguez, A; Fidalgo, T; Martinho, P; López-Fernández, MF; Rodríguez-Trillo, Á; Lourés, E; Parra, RLarge studies in von Willebrand disease patients, including Spanish and Portuguese registries, led to identification of >250 different mutations. It is a challenge to determine the pathogenic effect of potential splice site mutations on VWF mRNA. This study aimed to elucidate the true effects of 18 mutations on VWF mRNA processing, investigate the contribution of next-generation sequencing to in vivo mRNA study...
Combined study of ADAMTS13 and complement genes in the diagnosis of thrombotic ...
Fidalgo, T; Martinho, P; Pinto, CS; Oliveira, AC; Salvado, R; Borràs, N; Coucelo, M; Manco, L; Maia, T; Mendes, MJ; Del Orbe Barreto, R; Corrales, IBACKGROUND: The 2 main forms of thrombotic microangiopathy (TMA) are thrombotic thrombocytopenic purpura (TTP) and atypical hemolytic uremic syndrome (aHUS). Deficiency of ADAMTS13 and dysregulation of the complement pathway result in TTP and aHUS, respectively; however, overlap of their clinical characteristics makes differential diagnosis challenging. OBJECTIVES AND METHODS: We aimed to develop a TMA diagnosi...
Genotype-phenotype correlation in a cohort of Portuguese patients comprising th...
Fidalgo, T; Salvado, R; Corrales, I; Pinto, SC; Borràs, N; Oliveira, A; Martinho, P; Ferreira, G; Almeida, H; Oliveira, C; Marques, D; Gonçalves, ElsaThe diagnosis of von Willebrand disease (VWD), the most common inherited bleeding disorder, is characterised by a variable bleeding tendency and heterogeneous laboratory phenotype. The sequencing of the entire VWF coding region has not yet become a routine practice in diagnostic laboratories owing to its high costs. Nevertheless, next-generation sequencing (NGS) has emerged as an alternative to overcome this li...

Familial thrombotic risk based on the genetic background of Protein C Deficienc...
Fidalgo, T; Martinho, P; Salvado, R; Manco, L; Oliveira, AC; Pinto, CS; Gonçalves, E; Marques, D; Sevivas, T; Martins, N; Ribeiro, MLINTRODUCTION: Inherited protein C (PC) deficiency is a well-known risk factor for venous thrombosis (VT). Plasma PC levels are reliable in moderate to severe deficiencies; however, in mildly deficient individuals, the levels may overlap with those considered normal. Genetic studies of PROC, which encodes PC, could help identify carriers; genome-wide association studies (GWAS) have shown that approximately 50% o...
