Angelman syndrome is a rare neuro-genetic disorder caused by the loss of function of the maternal UBE3A gene on chromosome 15. In most healthy individuals, both parents contribute one copy of UBE3A, but only the maternal copy is active in neurons; the paternal copy is epigenetically silenced. When the maternal copy is missing or nonfunctional, the brain is unable to produce sufficient UBE3A protein, leading to the characteristic features of the syndrome: severe developmental delays, minimal or absent speech, movement disorders, frequent laughter or smiling, and seizures. First described by Dr. Harry Angelman in 1965 as “Puppet Children” due to their jerky, puppet-like movements, Angelman syndrome exemplifies genomic imprinting—a phenomenon where gene expression depends on the parent of origin NCBIMedlinePlus.
Angelman syndrome is a rare genetic neurodevelopmental disorder characterized by severe intellectual disability, minimal or absent speech, ataxic gait, seizures, and a distinctive “happy” demeanor with frequent laughter and smiling. Symptoms typically become noticeable between 6 and 12 months of age, when developmental delays—such as lack of babbling or crawling—first emerge. While individuals with Angelman syndrome often enjoy a near-normal life span, there is currently no cure; treatment focuses on symptom management and supportive therapies Mayo Clinic.
Angelman syndrome arises from loss of function of the maternal copy of the UBE3A gene on chromosome 15q11–q13. Normally, neurons express only the maternal UBE3A allele, as the paternal copy is silenced by a long noncoding RNA (UBE3A-ATS). When the maternal allele is deleted, mutated, or otherwise inactivated, neuronal development is disrupted, leading to the core features of Angelman syndrome Wikipedia.
Types of Angelman Syndrome
Angelman syndrome can arise through several distinct genetic mechanisms:
Maternal 15q11–q13 Deletion (≈70% of cases): A microdeletion removes UBE3A and neighboring genes from the maternal chromosome, abolishing UBE3A expression in neurons NCBI.
Paternal Uniparental Disomy (UPD) (≈2–7%): Two paternal copies of chromosome 15 are inherited, with no maternal copy to express UBE3A NCBI.
Imprinting Center Defect (≈3–5%): Errors in the imprinting control region cause the maternal UBE3A to be incorrectly silenced NCBI.
UBE3A Gene Mutation (≈5–10%): A point mutation or small inactivation within the maternal UBE3A gene prevents normal protein production NCBI.
Chromosomal Translocation or Rare Mechanisms (<1%): Structural rearrangements involving chromosome 15 can disrupt UBE3A expression Angelman Syndrome.
Causes of Angelman Syndrome
(Each bullet below describes a specific genetic mechanism or risk factor, explained in plain language.)
Maternal 15q11–q13 Deletion
A tiny segment of maternal chromosome 15, which includes the UBE3A gene, is lost before birth. Without this gene, neurons cannot make UBE3A protein. NCBIPaternal Uniparental Disomy (UPD)
Due to an error in egg or sperm formation, a child inherits two copies of chromosome 15 from the father and none from the mother, leaving no active maternal UBE3A. NCBIImprinting Center Defect
The “switch” that normally keeps the paternal UBE3A off and the maternal copy on becomes flipped, so both copies are treated like paternal and silenced. NCBIPoint Mutation in UBE3A
A single-letter change (mutation) in the DNA code of the maternal UBE3A gene prevents it from making the correct protein. NCBIChromosomal Translocation
Parts of chromosome 15 swap places with another chromosome in one of the parents. This rearrangement can break or silence the maternal UBE3A gene in the child. Angelman SyndromeEpigenetic Methylation Error
Chemical tags (methyl groups) that should be on the paternal copy end up on the maternal copy, turning it off when it should be active. NCBIMosaic Imprinting Defect
Some of the body’s cells silence maternal UBE3A while others do not, creating a patchwork (mosaic) pattern of normal and affected cells. Angelman SyndromeMicrodeletion of UBE3A Alone
A very small deletion removes only the UBE3A gene itself, sparing nearby genes but still eliminating UBE3A protein in neurons. FASTMaternal Balanced Translocation Carrier
A mother carries a swap between two chromosomes that doesn’t harm her because all genes are still present, but in her egg it becomes unbalanced and deletes UBE3A. ScienceDirectAdvanced Maternal Age-Related Nondisjunction
As eggs age, the risk of chromosome-splitting errors increases, raising the chance of deletions or UPD that underlie Angelman syndrome. Better Health ChannelGamete Meiotic Error
Random mistakes during the formation of sperm or egg cells can remove or silence the maternal UBE3A gene before conception. NCBIInherited Imprinting Centre Mutation
Rarely, families carry a mutation in the imprinting control region that is passed from parent to child, leading to recurrent Angelman syndrome. NCBIDe Novo (Spontaneous) Mutation
A fresh mutation appears in the child’s UBE3A gene that neither parent carries, causing the syndrome for the first time in the family. NCBIChromosomal Rearrangement Beyond 15q11–q13
Unusual rearrangements involving other chromosomes can indirectly disrupt the 15q11–q13 region and UBE3A expression. ScienceDirectUnknown (“Cryptic”) Genetic Variants
Even with advanced testing, about 5–10% of cases have no clear cause identified; novel or rare variations may underlie these unexplained cases. mastermindbehavior.com
