Main Search Index Definition Description Causes ... Resources Prader-Willi syndrome Definition Prader-Willi syndrome (PWS) is caused by a rare birth defect centered on chromosome 15. Characteristics of the syndrome include developmental delays and mental retardation , behavioral problems, and insatiable appetite leading to obesity . Affected individuals also experience incomplete sexual development, poor muscle tone, and short stature as adults. Description PWS occurs in 1 in 12,000 to 15,000 births and is regarded as the most common genetic cause of obesity. It affects both genders and all races. Although PWS arises from a genetic defect, it is not an inherited conditionit is a birth defect. The defect occurs spontaneously and specifically involves chromosome 15. A person normally inherits one copy of chromosome 15 from each parent. In PWS cases, the copy from the father either lacks a specific segment of DNA (70-75% of cases) or is missing altogether (25-30% of cases). If the father's chromosome 15 is absent, a person with PWS has two copies of the mother's chromosome 15. Although the individual has the proper number of chromosomes, inheriting two copies of a chromosome from one parent is an abnormal situation called uniparental disomy. If that parent is the mother, it is called maternal uniparental disomy. Virtually all parents of individuals with PWS have normal chromosomes; fewer than 2% of cases are linked to an inherited genetic mutation. In most cases, an error occurs during embryo development. This error leads to deletion of part of the father's chromosome 15 or to maternal uniparental disomy for chromosome 15. In either case, genes that should have been inherited from the father are missing and PWS develops.

Prader-Willi syndrome From Wikipedia, the free encyclopedia. Prader-Willi syndrome is a genetic disorder in which seven genes (or some subset thereof) on chromosome 15 are missing or unexpressed ( chromosome 15q, partial deletion ). It was discovered in by Andrea Prader, Heinrich Willi, Alexis Labhart, and Guido Fanconi of Switzerland Babies with Prader-Willi syndrome are born with low muscle tone and a weak sucking reflex. Once the muscles strengthen, however, their insatiable appetite takes over. They eat and eat, never feeling full. As they have a lower metabolism than normal people, they often end up obese if the kitchen isn't locked. This is caused by a misdevelopment of the hypothalamus The genes of Prader-Willi syndrome are expressed only on the paternal chromosome. The eighth gene in the segment, whose deletion causes Angelman syndrome , is expressed only on the maternal chromosome. It is thus possible for a woman with Prader-Willi syndrome to pass the mutation to her son, who has Angelman syndrome. This is the first known instance of imprinting in humans.

Normally, we inherit one copy of each chromosome pair from our biological mother, and the other copy of the chromosome pair from our biological father. Uniparental disomy refers to the situation in which two copies of a chromosome come from the same parent, instead of one copy coming from the mother and one copy coming from the father.

My Profile Last updated 06/02/04 12:24 PST Prader-Willi Syndrome Overview Prader-Willi Syndrome is a neurobehavioral genetic disorder affecting approximately 1:10,000 newborns. It occurs sporadically and there is no known cause. It is not inherited and is not related to medical, environmental or psychological factors. It occurs in both sexes and in all races. Characteristics include: obesity, short stature, mental deficiency, and a history of hypotonia (floppiness) in infancy. Prader-Willi Syndrome has many other features, but extreme obesity and health problems associated with obesity are the most prominent. Prader-Willi Syndrome has two diagnostic stages: Stage 1: "Floppy Babies" Hypotonia or atonia (weak muscles) are noted in infancy. There is generally improvement seen between eight and eleven months, but muscle tone is never normal. Sleepiness and feeding difficulties (associated with hypotonia and often requiring tube feedings) are also common at this stage.

Most cases of PWS are attributed to a spontaneous genetic error that occurs at or near the time of conception for unknown reasons. In a very small percentage of cases (2 percent or less), a genetic mutation that does not affect the parent is passed on to the child, and in these families more than one child may be affected. A PWS-like disorder can also be acquired after birth if the hypothalamus portion of the brain is damaged through injury or surgery.

Developmental Delay Down Syndrome Fragile X Syndrome Kleinfellers Syndrome ... Back to disorder categories Prader-Willi Syndrome Prader-Willi Syndrome, or PWS is a very rare and complex disorder. Common characteristics include Hypotonia during infancy, Hypogonadism and after the age of two, excessive weight gain and obesity. One of the most interesting characteristics of this disorder is the person's obsession with food and eating. Other characteristics of PWS include: stubbornness, depression, rage and periodic outbursts. Personality and emotional problems as well as behavioral disorders are also frequently found with those who suffer from PWS. There are no concrete cognitive problems associated with the disorder; however, studies have shown that academic weaknesses are commonly found in the understanding of time, money and writing. On the other hand, reading and language are oftentimes seen as strengths. Treatment for PWS is varies from person to person. Yet, the maintaining and reduction of food intake is the main objective when dealing with the disease. This should be done in both school and the home. Physical activities should be designed to encourage social interaction as well as promote self-awareness. In addition, academic weaknesses should be addressed while paying particular attention to the reduction of violent outbreaks and temper tantrums.

Educating Parents of Extra-special Children (EPEC) A resource of information for adults with special needs and parents with special needs children. Prader-Willi Syndrome Prader-Willi Syndrome is a disorder which is sometimes associated with, but not a subtype of, autism. The classical features of this disorder include an obsession with food which is often associated with impulsive eating, compact body build, underdeveloped sexual characteristics, and poor muscle tone. Because of their obsession with food, many people afflicted with Prader-Willi Syndrome are overweight. Most individuals afflicted with Prader-Willi Syndrome have mild mental retardation. Some of the behaviors which are common to both Prader-Willi Syndrome and autism are: delays in language and motor development, learning disabilities, feeding problems in infancy, sleep disturbances, skin picking, temper tantrums, and a high pain threshold. Prader-Willi Syndrome affects approximately 1 in 10,000 people. Most individuals suffering from this disorder are missing a small portion of chromosome 15 which appears to come from the paternal side of the family. When a small portion of chromosome 15 is missing and comes from the maternal side, the person may suffer from Angelman Syndrome. The most effective form of treatment for people suffering from Prader-Willi Syndrome is behavior modification. In general, medications do not appear to very effective for these individuals.
