This test, known as a DNA methylation test, screens for three of the four known genetic abnormalities that cause Angelman syndrome. This genetic testing can identify abnormalities in your child’s chromosomes that indicate Angelman syndrome.Ī combination of genetic tests can reveal the chromosome defects related to Angelman syndrome. TestsĪ definitive diagnosis can almost always be made through a blood test. Your child’s doctor may suspect Angelman syndrome if your child has developmental delays, specifically minimal or absent language, and other signs and symptoms of the disorder, such as seizures, problems with movement and balance, a small head size, and a happy demeanor. If you’re concerned about a family history of Angelman syndrome or if you already have a child with the disorder, consider talking to your doctor or a genetic counselor for help planning future pregnancies.

In rare cases, Angelman syndrome may be passed from an affected parent to a child through defective genes. Older children with Angelman syndrome tend to have large appetites, which may lead to obesity. Some people with Angelman syndrome develop an abnormal side-to-side spinal curvature over time. Medication and behavior therapy may help control sleep disorders. People with Angelman syndrome often have abnormal sleep-wake patterns and may require less sleep than most people. Hyperactivity often decreases with age, and medication usually isn’t necessary.

Children with Angelman syndrome often move quickly from one activity to another, have a short attention span, and keep their hands or a toy in their mouths. Your pediatrician may recommend a high-calorie formula to help your baby gain weight. Difficulty coordinating sucking and swallowing may cause feeding problems in infants. ComplicationsĬomplications associated with Angelman syndrome include: A family history of the disease may increase a baby’s risk of developing Angelman syndrome. Occasionally, Angelman syndrome may be inherited from a parent. Most people with Angelman syndrome don’t have a family history of the disease. Researchers usually don’t know what causes the genetic changes that result in Angelman syndrome. In a few cases, Angelman syndrome is caused when two paternal copies of the gene are inherited, instead of one from each parent. Most cases of Angelman syndrome occur when part of the maternal copy is missing or damaged. Normally, only the maternal copy of the UBE3A gene is active in the brain. Your cells typically use information from both copies, but in a small number of genes, only one copy is active. You receive your pairs of genes from your parents - one copy from your mother (maternal copy) and the other from your father (paternal copy). It’s usually caused by problems with a gene located on chromosome 15 called the ubiquitin protein ligase E3A ( UBE3A) gene. CausesĪngelman syndrome is a genetic disorder. If your child seems to have developmental delays or if your child has other signs or symptoms of Angelman syndrome, make an appointment with your child’s doctor. The first signs of Angelman syndrome are usually developmental delays, such as lack of crawling or babbling, between 6 and 12 months. Most babies with Angelman syndrome don’t show signs or symptoms at birth. Unusual behaviors, such as hand flapping and arms uplifted while walking.

People with Angelman syndrome often smile and laugh frequently, and have happy, excitable personalities.ĭevelopmental delays, which begin between about 6 and 12 months of age, are usually the first signs of Angelman syndrome. It causes delayed development, problems with speech and balance, intellectual disability, and, sometimes, seizures.
