What is Angelman syndrome?
Angelman syndrome is a complex genetic disorder that primarily affects the nervous system. Characteristic features of this condition include developmental delay, intellectual disability, severe speech impairment, and problems with movement and balance (ataxia). Most affected children also have recurrent seizures (epilepsy) and a small head size (microcephaly). Delayed development becomes noticeable by the age of 6 to 12 months, and other common signs and symptoms usually appear in early childhood. Children with Angelman syndrome typically have a happy, excitable demeanor with frequent smiling, laughter, and hand-flapping movements. Hyperactivity and a short attention span are common. Most affected children also have difficulty sleeping and need less sleep than usual. Some affected individuals have unusually fair skin and light-colored hair.

What is Angelman Syndrome?
Angelman syndrome is a rare genetic condition, the symptoms of which include severe learning difficulties, jerky movements and a happy disposition. Around 48 years ago, English physician Harry Angelman first described the condition that would later bear his name. However, the prevalence of Angelman syndrome was low and debate over its existence continued for many years. Angelman syndrome is generally considered to be a chromosomal disorder. Most cases can be traced to the partial deletion of a gene on chromosome 15. Chromosomes perform different functions throughout our body, but it is the way in which chromosome 15 functions in the brain that leads to the behaviours associated with Angelman syndrome.
Genetics
Everyone inherits chromosomes and genetic material from their mother and father. In the case of chromosome 15, the parts contributed by each parent function in different ways. For instance, only the maternal copy is active in the brain. If the mother's contribution to this particular chromosome has been deleted or, in some cases, replaced by a copy of the father's contribution, then this can result in Angelman syndrome. There is no known cause for this genetic abnormality. It is thought to happen when an unknown factor randomly goes awry in the normal reproductive process. The condition is not passed on from parent to child, nor does it run in families. Diagnosis of the syndrome usually occurs between the ages of three and seven. Development is delayed even at the youngest ages, but usually becomes apparent by the age of six months. The characteristic features of Angelman syndrome often take a few years to become noticeable. It is worth knowing that once the syndrome is diagnosed, genetic tests are commonly used to confirm the diagnosis.

From Wikipedia, the free encyclopedia Jump to: navigation search Angelman syndrome Classification and external resources ICD Q ICD OMIM ... MeSH Angelman syndrome (AS) is a neuro- genetic disorder characterized by intellectual and developmental delay , sleep disturbance, seizures , jerky movements (especially hand-flapping), frequent laughter or smiling, and usually a happy demeanor. AS is a classic example of genomic imprinting in that it is usually caused by deletion or inactivation of genes on the maternally inherited chromosome 15 while the paternal copy, which may be of normal sequence, is imprinted and therefore silenced. The sister syndrome, Prader-Willi syndrome , is caused by a similar loss of paternally-inherited genes and maternal imprinting. AS is named after a British pediatrician , Dr. Harry Angelman , who first described the syndrome in 1965. An older, alternative term for AS, happy puppet syndrome , is generally considered pejorative and stigmatizing so it is no longer the accepted term, though it is sometimes still used as an informal term of diagnosis. People with AS are sometimes known as "angels", both because of the syndrome's name and because of their youthful, happy appearance.

Angelman syndrome Genetics
September 1st, 2007 In the majority of families there is only one individual affected by Angelman syndrome. In these families the affected person usually has a piece of one of their chromosome 15s missing ( deletion ). Deletions can be detected down the microscope or by looking at a persons DNA, their genetic material using special techniques in the laboratory. In cases with a chromosome 15 the parents chromosome are usually absolutely normal. Neither parent is a carrier Angelman syndrome but the deletion in the child usually arises by chance on the chromosome 15 which came from the mother. If a similar deletion arises on the chromosome 15 which comes from the father, then a completely different condition called Prader-Willi syndrome results.

    The Genetics of Prader-Willi Syndrome:
    An Explanation for the Rest of Us Chromosome 15 - an explanation
    (Originally published in PWSAs The Gathered View by Linda Keder, former editor, March-May 2000. Revised and updated in July 2004 with the assistance of Merlin G. Butler, M.D. Ph.D., Chair, PWSA-USA Scientific Advisory Board.) When the medical world first learned about Prader-Willi syndrome in 1956, doctors had no idea what caused people to have this collection of features and problems that we now know as PWS. In 1981, Dr. David Ledbetter and his colleagues reported a first breakthrough discovery: Many people with PWS that they studied had the same segment of genes missing from one of their chromosomes. They had discovered the deletion on chromosome 15 that accounts for about 70 percent of the cases of PWS. Since then, researchers have made a series of other important discoveries about the genes involved in Prader-Willi syndrome. Thanks to their perseverance, we now know much more about the several genetic forms of this complex disorder, and we have genetic tests that can confirm nearly every case.
    Chromosomes and Genes: The Basics
    Changes or errors in genes and chromosomes are common in the formation of egg and sperm cells. Some of these genetic changes will have no effect when a baby is conceived; some will cause a miscarriage; and some, like those in Prader-Willi syndrome, will cause significant differences in how the baby develops and functions. While many genetic disorders are caused by a change in a single gene and can be passed down from parent to child, PWS is more complicated.
