Using human nerve cells and three-dimensional “mini brains,” researchers have found that dysfunctional potassium channels may underly the development of seizures associated with Angelman syndrome. Their study, “Potassium channel dysfunction in human neuronal models of Angelman syndrome,” was published in the journal Science.

GTX-102, a potential treatment for Angelman syndrome, is cleared for clinical trials, thanks to the activation of its investigational new drug (IND) application by the U.S. Food and Drug Administration. Enrollment in an upcoming Phase 1/2 trial is due to begin in the first half of…

Nutrition is an important but under-discussed aspect of care in Angelman syndrome (AS), according to a case report that described the use of a gastronomy button in a child with the disorder who also had a swallowing dysfunction. The report was published in Lifestyle Genomics and titled “…

A clinical trial is evaluating the safety and tolerability of a nutritional formulation containing the ketone beta-hydroxybutyrate (BHB) as a treatment to help control seizures in children with Angelman syndrome. More information about the trial (NCT03644693), called Nutritional Formulation for Angelman Syndrome (FANS), is available here. The…

Fertility treatments could make babies more prone to genetic errors that lead to the development of Angelman syndrome and other disorders, an early study in mice has found. Contrary to what was anticipated by researchers, older maternal age did not increase the frequency of such problems in mice, suggesting…

Despite being relatively healthy, adults with Angelman syndrome should be carefully monitored, particularly for weight control, vision and gastrointestinal issues, behavioral and sleep problems, and epilepsy, a study suggests. According to its authors, findings from this study, reported to have enrolled the largest and oldest group of adults with…

Clinicians should consider mosaic Angelman syndrome in the differential diagnosis of people who show milder symptoms of the disorder, a study suggests. The study, “Preserved expressive language as a phenotypic determinant of Mosaic Angelman Syndrome,” was published in Molecular Genetics & Genomic Medicine. Angelman syndrome (AS) is…

With so much recent publicity surrounding gene therapy, it’s no surprise that the topic was a major focus of the recent 2019 NORD Rare Diseases & Orphan Products Breakthrough Summit. From diagnosis and clinical trial design to manufacturing, pricing strategies, and ethical concerns, gene therapy — both its high…
