Prader–Willi syndrome

Prader-Willi Syndrome Prader-Willi Syndrome (PWS) is a rare genetic disorder presented at birth that results in numerous physical, cognitive, and behavioral problems, most notably food-related issues and obesity. Infants with PWS are characterized with severe low muscle tone, feeding difficulties, poor growth, and delayed development. Later on, these infants begin to eat excessively and become obese due to the hypothalamus not working properly. Most cases of PWS are not inheritable and are a result of an error that occurred in the region of chromosome 15. When diagnosing PWS, an individual’s patient history is looked at, a through clinical evaluation is given, and any characteristic symptoms are identified. All newborns and infants with an…

Prader-Willi syndrome is a genomic imprinting disorder caused by the failure to express SNRPN (small nuclear ribonucleoprotein-associated polypeptide N) gene product. SNRPN is expressed only on the paternal chromosome 15q11-q13, however, the exact genes responsible for Prader-Willi syndrome haven't been identified. People normally inherit one copy of chromosome 15 from each parent. Some genes are active only on the copy that is inherited from a person's father, the paternal copy. Genomic…

Understanding Prader-Willi Syndrome Embarking upon one of the most challenging and rewarding jobs can be overwhelming at times. This job being referred to is parenthood. Becoming a parent can definitely be arduous and yet satisfying to say the least. All across the world babies are born each day. That miraculous event is filled with excitement, worry, happiness, and apprehension. Parents are concerned and consumed with the safety and health of their precious children. Questions such as does the…

It is a defect on their chromosome 15, which affects one out of every 15000 births. Prader-Willi Syndrome (PWS) is a genetic disease that causes children to be hyperphagia meaning they…

Obesity is the condition when a person is overweight due to the excessive amount of fat being accumulated in the body. Obesity is caused because of some diseases, drugs, and unhealthy lifestyles. It is a growing global health problem. Genetic Diseases, such as the Prader-Willi Syndrome, can cause obesity. In children, the Prader-Willi Syndrome is genetically the most common cause of obesity. It is a disorder in which the 15th chromosome has an abnormality. The child will experience chronic…

behind the study, and why it needs to be conducted. For the potential subjects and their families these therapies might both be viewed as standards of care and therefore should yield a positive outcome. Oxytocin, the standard of care given to one third of the population, is used as a control. The subjects who receive this treatment, although not completely without risks, are given a known treatment to be effective in practice. Justification for the DBS treatment, is to measure the efficacy…

Dimitropoulos et al. (2000) states, “The intense preoccupation with food, lack of satiation, and incessant food seeking among people with PWS are the most striking features of the syndrome.” This in itself goes against Abraham Maslow’s hierarchy of needs. At the base of the pyramid of needs lies the physiological need for air, food, drink, shelter, warmth, sex, sleep. People with Prader Willi Syndrome never achieve the feeling of being full so in essence, their physiological need for food and…

Angelman syndrome is a rare genetic disorder that affects around 1 in around 12,000-20,000 live births and affects both males and females equally. Angelman syndrome is very often misdiagnosed as autism or cerebral palsy. Angelman syndrome is not an inherited disease, and is instead caused by a change in the E3 ubiquitin protein ligase gene (UBE3A) on the maternal chromosome 15. This change prevents the chromosome from functioning properly. It occurs as a random event during the formation of eggs…
