IntroductionAngelman syndrome (AS) is a rare condition with low prevalence associated with severe global developmental delay, behavioral phenotype of happy appearance and social interaction, moderate to severe intellectual disability with minimal or absent oral language associated with molecular etiology and featuring clinical variables. ObjectivesTo describe communication and language abilities in a sample of individuals with AS from Spain and Portugal, explore the influence of molecular etiology, age and use of Augmentative and Alternative Communication (AAC). Materials and methodsThe sample comprised 40 individuals diagnosed with AS, from the Iberian Peninsula, assessed using the MacArthur Communicative Development Inventories. ResultsA characteristic profile is shown with a predominance of gestures and receptive language over expressive. Differences are noted by molecular subtype, age, use of AAC and the origin in the Iberian Peninsula. ConclusionsThe linguistic phenotype for Angelman Syndrome is consistent with findings from other studies, however associated variables such as molecular etiology and use of AAC should be considered.
