Manipulation of the mechanism that controls UBE3A gene activation status in the brain may represent an alternative strategy to treat Angelman syndrome, a study suggests. The study, “A bipartite boundary element restricts UBE3A imprinting to mature neurons,” was published in the…

Scores of events are afoot worldwide to mark Feb. 28, Rare Disease Day 2019. The activities aim to raise awareness about rare diseases and the millions of people — estimates run as high as 350 million — they are thought to impact.

The U.S. Food and Drug Administration(FDA) is updating its 2015 draft guidelines for drug discovery in rare diseases, with new guidance on natural history— how disorders such as spinal muscle atrophy(SMA) run their course if untreated — the choice of “efficacy endpoints” in clinical trials, and how…

A clinical study has began to enroll patients with Angelman syndrome to explore the safety and tolerability of a nutritional formula supplemented with ketones for use in dietary interventions. This study is being conducted by Disruptive Nutrition, the keto-medical foods company subsidiary of Disruptive Enterprises, in collaboration with researchers…

Nonverbal patients with Angelman syndrome do not necessarily differentiate between known names — their own or those of others close to them — and unfamiliar names, as assessed through measurements of brain responses, a study suggests. The study, “Social–emotional processing in nonverbal individuals with Angelman syndrome:…

Coffin-Siris syndrome (CSS) should be included in the differential diagnosis of Angelman syndrome, say researchers, after describing the case of a 14-year-old boy who harbored a genetic mutation associated with CSS and experienced typical symptoms of Angelman syndrome. The findings were reported in the study, “Identification…

Nonverbal Angelman syndrome patients can learn new information by exposure to repeated auditory stimuli, a new study shows. Measuring brain electrical activity can help evaluate patients’ auditory learning and memory capacity. The study, “Feasibility of using auditory event-related potentials to investigate learning and memory in nonverbal individuals with Angelman…

With the addition of clinics in Canada and Israel, the Angelman Syndrome Foundation (ASF) now has an international network of Angelman Syndrome Clinics staffed with Angelman syndrome (AS) experts. The Children’s Hospital of Eastern Ontario (CHEO) in Ottawa, Canada, and the Edmond and Lily Safra…
