Angelman Syndrome (AS) Emerging Therapy and TPP Insights

Angelman Syndrome (AS) Overview

Angelman Syndrome is a neurogenetic disorder caused by loss of maternal UBE3A expression, impairing ubiquitin-mediated protein degradation and synaptic function. It presents with severe intellectual disability, absent speech, ataxic gait, seizures, and a characteristically happy demeanor. Diagnosis combines methylation analysis, UBE3A sequencing, and chromosomal microarray; seizure burden and functional impairment reflect severity. Seizure management incorporates valproate, levetiracetam, and cannabidiol, the latter offering efficacy in refractory myoclonic episodes with limited cognitive sedation. ASO therapies targeting UBE3A antisense transcripts to restore paternal gene expression are in advanced clinical trials. Regular neurodevelopmental monitoring, augmentative communication, and family-centred support underpin lifelong quality-of-life management.
