Other characteristics include short stature and intellectual disability. Treatment from healthcare professionals leads to improved quality of life Prader-Willi (PRAH-dur VIL-e) syndrome is a rare genetic disorder that results in a number of physical, mental and behavioral problems. A key feature of Prader-Willi syndrome is a constant sense of hunger that usually begins at about 2 years of age From Wikipedia, the free encyclopedia Prader-Willi syndrome (PWS) is a genetic disorder caused by a loss of function of specific genes on chromosome 15. In newborns, symptoms include weak muscles, poor feeding, and slow development

Prader-Willi syndrome is caused by some missing genetic material in a group of genes on chromosome number 15. This leads to a number of problems and is thought to affect part of the brain called the hypothalamus, which produces hormones and regulates growth and appetite Prader-Willi syndrome (PWS) is characterized by severe hypotonia and feeding difficulties in early infancy, followed in later infancy or early childhood by excessive eating and gradual development of morbid obesity (unless eating is externally controlled). Motor milestones and language development are delayed What Is Prader-Willi Syndrome?

Background: First described in 1956, Prader-Willi syndrome is a neurogenetic condition characterized by infantile hypotonia, hypogonadism and obesity. Mental deficiency, behavioral abnormalities, and obvious dysmorphic features are frequently found as well. It is a relatively common condition, with an incidence estimated to be between 1 in 10,000 to 25,000 live births The symptoms of Prader-Willi syndrome are believed to be caused by dysfunction of a portion of the brain called the hypothalamus. The hypothalamus is a small endocrine organ at the base of the brain that plays a crucial role in many bodily functions, including hunger and satiety, temperature and pain regulation, fluid balance, puberty, emotions, and fertility Prader-Willi syndrome, or PWS, is a genetic condition resulting from the loss of expression of paternal genes on chromosome 15. Individuals with PWS have low muscle tone, feeding issues in infancy, multiple endocrine issues and early-onset weight gain, can have compulsive and rigid behaviors, and typically develop an insatiable appetite later in childhood into adulthood Prader-Willi syndrome (PWS), a genetic disorder that usually involves chromosome 15, is the most common form of obesity caused by a genetic syndrome. Diagnosis often is delayed until early. Prader-Willi syndrome (PWS) is a complex neurobehavioral/metabolic disorder which is due to the absence of or lack of expression of normally active paternally expressed genes from the chromosome 15q11-q13 region. PWS can occur due to a de novo deletion in the paternally inherited chromosome region; because the individual inherited two copies.
