Angelman Syndrome: Understanding

Angelman Syndrome: Overview

Angelman syndrome (AS) is a rare neuro-genetic disorder that occurs in one in 15,000 live births or 500,000 people worldwide. It is caused by a loss of function of the UBE3A gene in the 15th chromosome derived from the mother. Angelman syndrome (AS) is characterized by severe developmental delay or intellectual disability, severe speech impairment, gait ataxia and/or tremulousness of the limbs, and unique behavior with an apparent happy demeanor that includes frequent laughing, smiling, and excitability. Angelman syndrome (AS) is characterized by severe developmental delay and intellectual disability, severe speech impairment, gait ataxia and/or tremulousness of the limbs, and a unique behavior with an apparent happy demeanor that includes frequent laughing, smiling, and excitability. Microcephaly and seizures are also common. Developmental delays are first noted at around age six months; however, the unique clinical features of AS do not become manifest until after age one year. Deficiency of the E3 ubiquitin protein ligase (UBE3A) gene expression causes Angelman syndrome. The gene is located in chromosome region 15 (15q11-q13). The abnormalities of UBE3A that can cause Angelman syndrome involve absence of the gene, changes in the structure of the gene, or changes in the function or expression of the gene. In approximately 70-75 percent of cases there is a microdeletion of region 15q11-13 of the maternally-derived chromosome 15 that includes deletion of the UBE3A gene. The diagnosis of AS is established in a proband who meets the consensus clinical diagnostic criteria and/or who has findings on molecular genetic testing that suggest deficient expression or function of the maternally inherited UBE3A allele. Analysis of parent-specific DNA methylation imprints in the 15q11.2-q13 chromosome region detects approximately 80% of individuals with AS, including those with a deletion, uniparental disomy, or an imprinting defect; fewer than 1% of individuals have a cytogenetically visible chromosome rearrangement (e.g., translocation or inversion). UBE3A sequence analysis detects pathogenic variants in an additional approximately 11% of individuals. Anti-seizure medication for seizures. Accommodation for hypermotoric behaviors and disruptive nighttime wakefulness. Behavior modification can be effective for disruptive or self-injurious behaviors. Physical therapy, occupational therapy, and speech therapy with an emphasis on nonverbal methods of communication, including augmentative communication aids (e.g., picture cards, communication boards) and signing. Individualization and flexibility in school settings.

Angelman Syndrome Emerging Drugs Chapters

This segment of the Angelman Syndrome report encloses its detailed analysis of various drugs in different stages of clinical development, including phase II, I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Angelman Syndrome Emerging Drugs

• NNZ-2591: Neuren Pharmaceuticals

NNZ-2591 is an analog of cyclic glycine proline, a peptide (small protein) that exists naturally in the brain and is important for the development of neurons (nerve cells). NNZ-2591 was tested in the ube3a knockout mouse model, which resembles features of Angelman syndrome in humans and includes motor deficits, learning problems and alterations in synaptic connectivity and plasticity. The study compared normal mice and ""knockout mice"" with a disrupted gene. In the knockout mice, treatment with NNZ-2591 for 6 weeks normalized the deficits in all the tests of anxiety, daily living, sociability, motor performance and cognition as well as eliminating seizures.

• GTX-102: Ultragenyx Pharmaceutical

GTX-102 is an investigational antisense oligonucleotide (ASO) therapy designed to inhibit expression of UBE3A-AS in order to prevent silencing of the paternally inherited allele of the UBE3A gene and reactivate expression of the deficient protein. GTX-102 is delivered as an intrathecal infusion. A Phase 1/2 study evaluating the tolerability and safety of GTX-102 and its effect on all major domains of the AS in pediatric patients is currently ongoing in the U.S., U.K. and Canada.
