Genomic imbalances defining novel intellectual disability associated loci
Lopes, Fátima; Torres, Fátima; Soares, Gabriela; Barbosa, Mafalda; Silva, João; Duque, Frederico; Rocha, Miguel; Sá, Joaquim; Oliveira, GuiomarBackground: High 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...

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...
