FAST’s Roadmap is focused on three elements supporting therapeutic approaches that have the potential to reverse the effects of the disorder in children, teens and adults.
Gene activation therapy, in AS referred to as “stop the stop”, works to activate the normally silent paternal gene to compensate for the underperforming or missing maternally inherited gene. Treatment is delivered via ASO, ATO, or CRISPR.
The Emergency Care Consortium will provide a global emergency and urgent care hotline. The hotline will be free of charge, available 24-hours a day and seven days a week, and will enable provider-to-provider consultations to manage urgent issues with the appropriate standards directly related to Angelman syndrome, especially seizures. More than 90% of individuals with Angelman syndrome experience seizures which are often difficult to control with traditional seizure medications. The Emergency Care Consortium will be available for provider-to-provider use in July 2021, with clinical experts that truly understand the nuances unique to Angelman syndrome.
Dr. Keung and his team at North Carolina State University will provide the Angelman syndrome research community a set of cell lines that can be used to efficiently model the biology of ICD and UPD, as well as organoids that model the mosaic genotype. This will aim to help understand any potential impact of gene overexpression in these different genotypes.
This grant focuses on the development of a microRNA approach as a potential therapeutic for the treatment of Angelman syndrome. In collaboration with the Gene Therapy Program at the University of Pennsylvania, the latest research plan will build on the milestones already achieved with CRISPR-Cas9/sgRNA interference of the UBE3A-antisense transcript (UBE3A-AS) to develop a novel strategy to suppress UBE3A-AS extension utilizing microRNAs as a potential one-and-done treatment option.
