Angelman Syndrome in Grand Rapids, Michigan

Angelman syndrome is a rare genetic condition that is present at birth (congenital) and affects the nervous system. Families in Grand Rapids, MI who receive this diagnosis often work closely with pediatric specialists at local centers such as Corewell Health (formerly Spectrum Health) Helen DeVos Children’s Hospital, Trinity Health Grand Rapids, Metro Health – University of Michigan Health, and Mercy Health.

Angelman syndrome most often occurs when a specific gene called UBE3A, located on chromosome 15, is missing (deleted) or not working properly. This gene is especially important in certain areas of the brain.

What Is Angelman Syndrome?

In most people, the UBE3A gene from both parents is active throughout the body. However, in some parts of the brain, only the copy inherited from the mother is normally active. If this maternal copy is missing or not working, the brain does not make enough UBE3A protein, which is believed to cause the features of Angelman syndrome.

Angelman syndrome is rare, affecting an estimated 1 in 10,000 to 1 in 20,000 children. Most children are diagnosed between 2 and 5 years of age, often after parents or pediatricians notice delayed development, speech difficulties, or seizures.

Common Features and Symptoms

Core Developmental and Neurological Features

Children with Angelman syndrome typically have:

  • Intellectual disability – delayed development in most areas (motor skills, language, self-care)
  • Severe speech delay or no speech – many children may use only a few words or none at all and rely on non-verbal communication
  • Delayed motor milestones – sitting, crawling, and walking later than peers
  • Problems with balance and coordination (ataxia)
  • Jerky, puppet-like movements and a stiff-legged walking style
  • Hand flapping or other repetitive movements
  • Very short attention span and hyperactive behavior

Behavioral and Emotional Characteristics

Many families in Grand Rapids report that, despite challenges, their child with Angelman syndrome has a very engaging personality. Common behavioral traits include:

  • Loving, happy, and highly social demeanor
  • Frequent smiling and laughter
  • Strong interest in people and social interaction

Angelman syndrome was once called “happy puppet syndrome” because of the combination of jerky movements and a cheerful appearance. This term is no longer used because it is considered insensitive. The condition is now known as Angelman syndrome, named after Dr. Harry Angelman, who first described it in 1965.

Physical and Neurological Signs

Some physical and neurological features that may develop over time include:

  • Small head size (microcephaly)
  • Flattened back of the head (microbrachycephaly)
  • Deep-set eyes
  • Wide, often smiling mouth
  • Prominent jaw and widely spaced teeth
  • Lightly pigmented hair, skin, and eyes (in some children)
  • Characteristic brainwave abnormalities on EEG, even without seizures

Epilepsy and Sleep

  • Epilepsy occurs in more than 80% of individuals with Angelman syndrome. Seizures often begin in early childhood.
  • Disturbed sleep is common, with difficulty falling or staying asleep.

Daily Living Challenges

Many children and adults with Angelman syndrome may experience:

  • Feeding difficulties, especially in infancy
  • Delayed toilet training – about 80% of adults are dry during the day, but nighttime continence may remain difficult
  • Ongoing support needs with self-care and daily routines

In Grand Rapids, pediatric neurologists, developmental pediatricians, and therapists at local hospitals and clinics can help manage these symptoms and support families.

Causes of Angelman Syndrome

Angelman syndrome is caused by problems with the UBE3A gene on chromosome 15, usually involving the copy inherited from the mother. The main known causes include:

  1. Deletion of maternal chromosome 15 segment (~68%)

    • A section of genetic material that normally contains the UBE3A gene is missing from the mother’s copy of chromosome 15.
    • The mother’s chromosome is usually normal; the deletion occurs during egg development.

  2. Mutation in the UBE3A gene (~11%)

    • The UBE3A gene is present but changed (mutated) so it cannot function normally.

  3. Paternal uniparental disomy (UPD) (~7%)

    • The child inherits two copies of chromosome 15 from the father and none from the mother.
    • Because the maternal copy is needed for UBE3A expression in certain brain areas, UBE3A is not properly produced.

  4. Imprinting center defects or other deletions (~3%)

    • A problem in another region of chromosome 15 disrupts the normal “imprinting” process, shutting off the maternal UBE3A gene.

  5. Unknown cause (~11%)

    • In some children, standard testing does not identify a specific cause, although the clinical features clearly suggest Angelman syndrome.

In all these cases, the result is the same: little or no functional UBE3A protein in certain parts of the brain, which leads to the characteristic features of Angelman syndrome.

Diagnosis of Angelman Syndrome in Grand Rapids

Clinical Evaluation

Diagnosis usually begins when a pediatrician or family notices:

  • Significant developmental delays
  • Absent or minimal speech
  • Unusual gait or movement patterns
  • Seizures
  • Characteristic behaviors (frequent laughter, social personality)

A detailed medical history, physical exam, and neurological assessment are performed. Because Angelman syndrome shares features with other conditions, careful evaluation is essential.

Conditions That Can Look Similar

Angelman syndrome may be confused with:

  • Autism spectrum disorder (ASD) – due to hyperactivity, hand flapping, and speech delay. However, children with Angelman syndrome are typically highly social, while some children with autism may avoid eye contact or social interaction.
  • Rett syndrome
  • Lennox-Gastaut syndrome
  • Non-specific cerebral palsy

It is also possible for a child to have both Angelman syndrome and autism, so specialized assessment is important.

Genetic Testing

Definitive diagnosis usually involves DNA and chromosomal testing, which may include:

  • Methylation studies of chromosome 15
  • Deletion/duplication analysis
  • UBE3A gene sequencing
  • Testing for uniparental disomy or imprinting defects

Families in Grand Rapids can often access genetic testing through:

  • Pediatric genetics clinics at Corewell Health / Helen DeVos Children’s Hospital
  • Trinity Health Grand Rapids or Metro Health – University of Michigan Health genetics services
  • Referral from a local pediatrician or family doctor

Treatment and Management in Grand Rapids, MI

There is no cure for Angelman syndrome, but early and ongoing treatment can significantly improve quality of life. Care is focused on managing symptoms and maximizing each child’s abilities.

Medical Management

  • Anti-epileptic medications to control seizures
  • Sleep management, which may include behavioral strategies and, in some cases, medication
  • Monitoring for orthopedic issues, such as scoliosis or joint problems

In West Michigan, pediatric neurologists at Helen DeVos Children’s Hospital and other Grand Rapids hospitals frequently manage epilepsy and complex neurological needs.
