Autism Spectrum Disorder: gene variants involved in the nonsense-mediated mRNA ...
Marques, Ana Rita; Martiniano, Hugo; Santos, J.X.; Vilela, Joana; Asif, M.; Rasga, C.; Oliveira, G.; Romão, Luísa; Vicente, AstridGenetic factors account for 50-80% of the familial risk of Autism Spectrum Disorder (ASD), but most of the genetic determinants are still unknown and a role for other regulatory mechanisms is likely. The nonsense-mediated decay (NMD) pathway is essential to control mRNA quality and has an important role in the regulation of the transcriptome. Mutations in genes involved in the NMD pathway, such as the UPF3B gen...
A role for gene-environment interactions in Autism Spectrum Disorder is suggest...
Santos, J.X.; Marques, A.R.; Rasga, C.; Asif, M.; Vilela, J.; Martiniano, H.; Oliveira, G.; Nunes, A.; Vicente, A.M.Objective: Identify potentially pathogenic CNVs and SNVs targeting genes involved in regulation of toxins exposure, namely in detoxification processes and physiological permeability barriers (blood-brain barrier and placenta), in individuals with ASD.
Adapting the early life exposure assessment tool (ELEAT) to Portugal: a pilot s...
Rasga, C.; Santos, J.; Lopes, A.L.; Marques, A.R.; Vilela, J.; Asif, M.; Walker, C.K.; Schmidt, R.J.; Vicente, A.M.The objective was to pilot a Portuguese version of the Early Life Exposure Assessment Tool (ELEAT) for the assessment of the role of environmental exposures in a population of Portuguese children with ASD.
An integrative system biology approach for dissecting Autism Spectrum Disorder
Asif, M.; Rasga, C.; Martiniano, H.; Santos, J.X.; Marques, A.R.; Couto, F.M .; Vicente, A.M.Autism Spectrum Disorder (ASD) is characterized by a wide spectrum of behavioral presentation. Many genetic factors are implicated in ASD, however their role in the heterogeneous ASD phenotype remains elusive. Using data mining-based integrative approaches, we seek to identify patterns of association between ASD phenotypic subgroups and altered biological processes inferred from CNVs targeting brain genes.
ASD prevalence study across Europe: developing a school-based screening approac...
García Primo, P.; Schendel, D.; Partner, E.; Rasga, C.; Café, C.; Rogé, B.; Arnaud, C.; Saemundsen, E.; Muratori, F.; Narzisi, A.; Boilson, A.Objectives: The main objective of the present work is to describe the strategy of the Autism Spectrum Disorder in the European Union (ASDEU) project to estimate the prevalence of ASD in school-aged children (7-9 years) across Europe. The focus of the presentation is on the novel field study strategy and aims to be a reflection on what we have learned regarding standardization of study methods across sites, what...
CNVs targeting genes that regulate exposure to toxicants in Autism Spectrum Dis...
Santos, J.X.; Rasga, C.; Asif, M.; Marques, A.R.; Vicente, A.M.Objective: Our overall goal is to identify genes involved in detoxification and regulation of barrier permeability processes that can mediate the effect of exposure to toxicants in individuals with ASD. For this purpose, we screened large ASD and control datasets for CNVs targeting selected detoxification and barrier permeability genes.
Increased frequency of the autism broader phenotype in mothers transmitting eti...
Asif, M.; Conceição, I.C.; Kwiatkowska, K.; Rasga, C.; Café, Cátia; Sousa, L.; Oliveira, G.; Couto, M.F.; Vicente, A.M.Introduction: Autism Spectrum Disorder (ASD) is a frequent and complex neurodevelopmental disorder, characterized by impairments in social communication and repetitive behaviors and with a high male to female ratio: ~4:1. Genetic factors, including rare Copy Number Variants (CNVs), have a substantial impact in ASD risk 1, and are associated with specific phenotypic manifestations 2. Recent studies reported that...
