- Adapting the early life exposure assessment tool (ELEAT) to Portugal: a pilot study to tackle gene-environment interactions in autism spectrum disorderPublication . 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.

- Evidence for a role of nonsense-mediated mRNA decay pathway genes in Autism Spectrum DisorderPublication . Marques, Ana Rita; Martiniano, H.; Santos, J.X.; Vilela, J.; Asif, M.; Oliveira, G.; Romão, L.; Vicente, A.M.Autism Spectrum Disorder (ASD): is a neurodevelopmental disorder characterized by deficits in social communication/interaction and by unusual repetitive and restricted behaviors and interests.
- Evidence for a role of nonsense-mediated mRNA decay pathway genes in Autism Spectrum DisorderPublication . Marques, Ana; Martiniano, Hugo; Santos, J.X.; Vilela, J.; Asif, M.; Oliveira, G.; Romão, Luísa; Vicente, AstridIntroduction: Autism Spectrum Disorder (ASD) is a highly heterogeneous neurodevelopmental disorder with an unclear etiology. Genetic factors are estimated to account for 50 to 80% of the familial ASD risk, but most of the genetic determinants are still not known and a role for other regulatory mechanisms is likely. The nonsense-mediated decay (NMD) pathway controls mRNA quality and plays an important role in the regulation of the transcriptome. Mutations in genes involved in the NMD pathway have been linked to neurodevelopmental disorders, with intriguing evidence for an involvement of mutations in the UPF3B gene, a core component of the NMD pathway, in ASD.
- miRNA and lncRNA gene variants in Autism Spectrum DisorderPublication . Marques, Ana Rita; Martiniano, H.; Santos, J.X.; Vilela, J.; Asif, M.; Oliveira, G.; Enguita, F.J.; Romão, L.; Vicente, A.M.Introduction: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder: Characterized by deficits in social communication/interaction and by unusual repetitive and restricted behaviors and interests; Median estimated prevalence worldwide is 17/10000; Male to female ratio: ~4:1; Comorbidities: intellectual disability, anxiety, epilepsy, (…).
- Regulatory RNA genes are targeted by Copy Number Variation in Autism Spectrum DisorderPublication . Marques, A.R.; Martiniano, H.; Santos, J.X.; Vilela, J.; Asif, M.; Oliveira, G.; Romão, L.; Vicente, A.M.Autism Spectrum Disorder (ASD) is a highly heterogeneous neurodevelopmental disorder with an unclear etiology. Genetic factors are estimated to account for 50 to 80% of the familial ASD risk, but most of the genetic determinants are still not known and a role for epigenetic factors is likely. The involvement of noncoding RNAs in ASD is, so far, insufficiently explored. MicroRNA (miRNA) and long noncoding RNA (lncRNA) are regulatory molecules, abundantly expressed in the brain, that play an important role during early stages of neural development. In this work we sought to address their potential role as ASD candidates, by identifying Copy Number Variants (CNVs) targeting miRNA and lncRNA genes in a large cohort of ASD patients, and examined their target genes and biological pathways.
- Regulatory RNAs in Autism Spectrum DisorderPublication . Marques, Ana Rita; Martiniano, H.; Santos, J.X.; Vilela, J.; Asif, M.; Oliveira, G.; Enguita, F.J.; Romão, L.; Vicente, A.M.Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder: Characterized by deficits in social communication/interaction and by unusual repetitive and restricted behaviors and interests.
- A role for gene-environment interactions in Autism Spectrum Disorder is suggested by an excess of potentially pathogenic variants in genes regulating exposure to toxicantsPublication . 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.
