RESUMENEl síndrome de Angelman es un trastorno neurogenético debido a la falta o reducción en la expresión del gen UBE3A en el cromosoma 15, el cual codifica la proteína ubiquitina ligasa E3A, que tiene un papel integral en el desarrollo sináptico y la plasticidad neuronal. Se manifiesta por retraso en el neurodesarrollo o discapacidad intelectual, comportamiento característico y epilepsia. Se describen las características clínicas de siete pacientes con deleción del cromosoma 15q11-13 y su manejo integral. Por la expectativa de vida, es importante conocer y manejar las comorbilidades de forma interdisciplinaria para lograr mejorar la calidad de vida de los afectados. Se realiza una revisión de la literatura sobre la aproximación integral al diagnóstico y cuidado clínico a largo plazo de los pacientes con síndrome de Angelman.

ABSTRACTAngelman syndrome is a neurogenetic disorder caused by a lack or reduction of expression of UBE3A located within chromosome 15, which codes for ubiquitin protein ligase E3A, which has a key role in synaptic development and neural plasticity. Its main features are developmental delay/intellectual disability, lack of speech, a characteristic behavioural profile, and epilepsy. We describe clinical features and management of seven cases with 15q11-13 deletion. Due to their life expectancy, knowing and managing its comorbidities is crucial to improve their quality of life. We review the diagnosis and long-term clinical care of patients with Angelman syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
