Angelman Syndrome is a rare genetic disorder that affects the nervous system. It is characterized by developmental delays, intellectual disabilities, speech impairments, and a happy demeanor. Individuals with Angelman Syndrome often have a characteristic appearance, including a wide mouth and widely spaced teeth.
Angelman Syndrome is caused by a deletion or mutation in the UBE3A gene on chromosome 15. This gene is responsible for producing a protein that is essential for normal brain development. In most cases, Angelman Syndrome is not inherited and occurs spontaneously.

Understanding Pedigree Charts
A pedigree chart is a visual representation of a family’s genetic history. It shows the relationships between family members and can help identify patterns of inheritance for genetic disorders like Angelman Syndrome. In a pedigree chart, individuals are represented by symbols, with different shapes and colors indicating different characteristics.
When creating a pedigree chart for Angelman Syndrome, individuals with the disorder are usually denoted by a shaded symbol. Family members who carry the genetic mutation but do not show symptoms may be represented by a half-shaded symbol. By analyzing a pedigree chart, genetic counselors and healthcare professionals can determine the likelihood of Angelman Syndrome being passed down in a family.
How to Create an Angelman Syndrome Pedigree Chart
To create an Angelman Syndrome pedigree chart, start by gathering information about your family members, including any known cases of the disorder. Use a pedigree chart template or software to organize this information in a clear and structured manner. Remember to include details such as the age, gender, and health status of each family member.
Once you have filled in the necessary information, analyze the chart to identify any patterns or trends that may indicate a risk of Angelman Syndrome in future generations. Consult with a genetic counselor or healthcare provider to interpret the results and discuss any potential implications for your family’s health.
