How does a child get Angelman syndrome?
In a small number of cases, Angelman syndrome happens when a child gets 2 copies of the gene from their father, rather than 1 from each parent. Sometimes the cause of Angelman syndrome is unknown. Most children in these unexplained cases have different conditions involving other genes or chromosomes.
What is the most common cause of Angelman syndrome?
Most cases of Angelman syndrome (about 70 percent) occur when a segment of the maternal chromosome 15 containing this gene is deleted . In other cases (about 11 percent), Angelman syndrome is caused by a mutation in the maternal copy of the UBE3A gene.
What is the life expectancy of a child with Angelman syndrome?
Some of the characteristic features of Angelman syndrome are a result from the loss of function of a gene called UBE3A. The life expectancy for individuals with Angelman syndrome appears to be nearly normal.
Who usually gets Angelman syndrome?
Angelman syndrome (AS) is a rare neuro-genetic disorder that occurs in one in 15,000 live births or 500,000 people worldwide. It is caused by a loss of function of the UBE3A gene in the 15th chromosome derived from the mother.
Are people with Angelman Syndrome actually happy?

Can someone with Angelman syndrome reproduce?
A male with Angelman syndrome caused by a deletion would be predicted to have a 50% chance of having a child with Prader-Willi syndrome (due to paternally inherited deletion of chromosome 15), although male fertility has not been described to date.

What organs are affected by Angelman Syndrome?
Angelman syndrome is a genetic disorder that primarily affects the nervous system. Characteristic features of this condition include developmental delay , intellectual disability , severe speech impairment, problems with movement and balance ( ataxia ), epilepsy , and a small head size.
Is Angelman syndrome recessive or dominant?
Originally it was thought that Angelman syndrome was caused by an autosomal recessive trait. However, Wagstaff and colleagues in 1992, discovered three sisters who all had affected offspring involving chromosome 15q11. This could mean that Angelman syndrome is either affected by inheriting an autosomal dominant allele or it is genomic imprinting.
How rare is Angelman syndrome?
Angelman Syndrome (AS) is a rare neurological disorder affecting around 1:20,000 births.
When was Angelman syndrome first discovered?
