Understanding Angelman Syndrome: Key Symptoms Revealed

Understanding Angelman Syndrome

Angelman Syndrome is a rare neurodevelopmental disorder that affects approximately 1 in 12,000 to 20,000 individuals. It is characterized by a distinct pattern of symptoms and behaviors that impact various aspects of a person's development and daily life.

‍

What is Angelman Syndrome?

Angelman Syndrome is a genetic disorder caused by a loss or dysfunction of the UBE3A gene, which is located on chromosome 15. This gene is responsible for producing a protein that plays a crucial role in the development and function of the nervous system. In individuals with Angelman Syndrome, the UBE3A gene is either missing or not working properly in certain regions of the brain.

The exact cause of the UBE3A gene dysfunction can vary. In approximately 70% of cases, the absence or malfunction of the UBE3A gene is due to a deletion of a portion of chromosome 15 that contains this gene. In other cases, Angelman Syndrome can result from mutations or other genetic abnormalities that affect the UBE3A gene.

The Genetic Basis of Angelman Syndrome

Angelman Syndrome follows an imprinting pattern, meaning that the UBE3A gene is only active when inherited from the mother's side. This is referred to as "imprinted" because the UBE3A gene on the father's chromosome 15 is typically silenced in certain regions of the brain.

When the UBE3A gene is absent or not functioning on the maternal chromosome, it leads to a lack of UBE3A protein in the affected areas of the brain. This deficiency disrupts the normal development and functioning of neurons, resulting in the characteristic symptoms of Angelman Syndrome.

Understanding the genetic basis of Angelman Syndrome is essential for accurate diagnosis and management of the condition. If you would like to learn more about the diagnostic process for Angelman Syndrome, please refer to their article on angelman syndrome diagnosis.
