Overview of Clinical Services

Angelman syndrome is a genetic disorder characterized by developmental delay, speech impairment, severe intellectual disability, microcephaly, seizures, movement disorder and a happy demeanor with frequent laughter. Other symptoms may include feeding and swallowing problems, sleep disturbance, hyperactivity, frequent drooling, mouthing behaviors, strabismus, hypopigmentation, scoliosis and constipation. Angelman syndrome is caused by a disruption of the expression or function of the UBE3A gene located on the maternal chromosome 15 (q11q13). Most individuals with Angelman syndrome (68%) have a deletion at 15q11q13. Approximately 7% have uniparental disomy (UPD), 3% have an imprinting center defect and 11% have mutations in the UBE3A gene.

The UNC Comprehensive Angelman Syndrome Clinic brings together multiple subspecialists into one setting to address the complex medical and psycho-educational needs of individuals with Angelman syndrome. Depending on the specific concerns, patients and their families have access to a clinical geneticist, neurologist, psychiatrist, psychologist, speech language pathologist, physical therapist, occupational therapist, genetic counselor, and social worker. All team members have expertise in service provision for individuals with developmental disabilities, including those with significant cognitive, language and physical limitations.

During the clinic visit, the patient and their family members and/or care providers will meet with each subspecialist to discuss relevant concerns. Following the consultations, the team will provide the family with a summary of their impressions and management recommendations. With family consent, the team will communicate directly with primary care physicians and other allied health professional in the patient’s medical home to provide direct consultation. Additional referrals to other subspecialists within the UNC Hospital system are also possible. Follow-up visits in the clinic will be determined based on each individual’s needs.
