Genomic imbalances defining novel intellectual disability associated loci
Lopes, Fátima Daniela Teixeira; Torres, Fátima; Soares, Gabriela; Barbosa, Mafalda; Silva, João; Duque, Frederico; Rocha, Miguel; Sá, JoaquimHigh resolution genome-wide copy number analysis, routinely used in clinical diagnosis for several years, retrieves new and extremely rare copy number variations (CNVs) that provide novel candidate genes contributing to disease etiology. The aim of this work was to identify novel genetic causes of neurodevelopmental disease, inferred from CNVs detected by array comparative hybridization (aCGH), in a cohort of 3...

Identification of rare de novo epigenetic variations in congenital disorders
Barbosa, Mafalda; Joshi, Ricky S.; Garg, Paras; Martin-Trujillo, Alejandro; Patel, Nihir; Jadhav, Bharati; Watson, Corey T.; Gibson, WilliamCertain human traits such as neurodevelopmental disorders (NDs) and congenital anomalies (CAs) are believed to be primarily genetic in origin. However, even after whole-genome sequencing (WGS), a substantial fraction of such disorders remain unexplained. We hypothesize that some cases of ND-CA are caused by aberrant DNA methylation leading to dysregulated genome function. Comparing DNA methylation profiles from...
Coffin-Siris syndrome and the BAF complex: genotype-phenotype study in 63 patients
Santen, Gijs W. E.; Aten, Emmelien; Vulto-van Silfhout, Anneke T.; Pottinger, Caroline; van Bon, Bregje W. M.; van Minderhout, Ivonne J. H. M.De novo germline variants in several components of the SWI/SNF-like BAF complex can cause Coffin-Siris syndrome (CSS), Nicolaides-Baraitser syndrome (NCBRS), and nonsyndromic intellectual disability. We screened 63 patients with a clinical diagnosis of CSS for these genes (ARID1A, ARID1B, SMARCA2, SMARCA4, SMARCB1, and SMARCE1) and identified pathogenic variants in 45 (71%) patients. We found a high proportion ...
A rare case of Beckwith–Wiedemann syndrome caused by a de novo microduplication...
Ferreira, Cristina; Marques, Bárbara; Alves, Cristina; Barbosa, Mafalda; Fortuna, Ana; Reis-Lima, Margarida; Correia, HildebertoBeckwith–Wiedemann syndrome (BWS) is a disorder of growth regulation exhibiting somatic overgrowth and predisposition to paediatric tumours. With an incidence estimated at 1 in 13,700, it is caused by various epigenetic and/or genetic alterations associated with disturbances within two different 11p15 domains that are controlled by distinct imprinting control regions (ICR), ICR1 and ICR2. The majority of patien...
Osteopathia striata with cranial sclerosis.
Barbosa, Mafalda; Perdu, Bram; Senra, Virgílio; Macedo, Filipe; Van Hul, Wim; Reis-Lima, Margarida; Pinto-Basto, JorgeWe report on a female patient who presented failure to thrive, laryngotracheomalacia, conductive deafness and facial dysmorphisms. A skeletal survey revealed thickening of the cranial vault, linear striations in the diametaphyses of all long bones and fan-like striations of the iliac bones. CT scan of the temporal bone showed thickening of the cranial base, sclerotic mastoids, abnormal ossicular fixation and st...
Exploring interpersonal dynamics between adults and motor disabled children wit...
Santos, Pedro Lopes dos; Teixeira, Luis Miguel Lopes; Azevedo, Maria; Barbosa, MafaldaThis paper focuses on interpersonal dynamics between the child with disabilities and the adult monitoring his/her performance in Aesthetic Resonance Environments. Drawing upon a social constructivist approach, a framework for human interactivity was checked against empirical data obtained from the exploratory implementation of an environment intending to stimulate body awareness and enhance movement in a group ...
