Most cases of Angelman syndrome are not inherited, particularly those caused by a deletion in the maternal chromosome 15 or by paternal uniparental disomy . These genetic changes occur as random events during the formation of reproductive cells (eggs and sperm) or in early embryonic development.

Are ears inherited from mom or dad?

Every person will inherit genes from their parents that affect the shape, size, and prominence of their ears. It is not uncommon to see large, protruding ears passed down from parent to child.

How do you explain chromosomes to a child?

Does my child have Angelman syndrome?

The first signs of Angelman syndrome are usually developmental delays, such as lack of crawling or babbling, between 6 and 12 months. 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.

Is Angelman syndrome paternal imprinting?

Considerable evidence suggests that the gene or genes responsible for Angelman syndrome are expressed only from the maternal chromosome 15, a situation known as parental imprinting.
