As an infant Vallejo had a decent appetite, and any initial weight gain was thought to have been a good sign, as both medical and aesthetic standards of the age considered slightly heavier frames on women to be preferable. By the time she was a year old she had already reached 25 kg (55 lbs). [3] By the age of six Vallejo weighed 70 kg (155 lbs).
Prader–Willi syndrome (PWS) is a rare genetic disorder caused by a loss of function of specific genes on chromosome 15. [2] In newborns, symptoms include weak muscles, poor feeding, and slow development. [2] Beginning in childhood, those affected become constantly hungry, which often leads to obesity and type 2 diabetes. [2]

Prader–Willi (PWS) and Angelman syndrome (AS) are distinct neurogenetic disorders caused by chromosomal deletions, uniparental disomy or loss of the imprinted gene expression in the 15q11-q13 region. Whether an individual exhibits PWS or AS depends on if there is a lack of the paternally expressed gene to contribute to the region.
Andrea Prader (December 23, 1919 – June 3, 2001) was a Swiss scientist, physician, and pediatric endocrinologist. He co-discovered Prader–Willi syndrome and created two physiological sex development scales, the Prader scale and the orchidometer .
People normally have two copies of this chromosome in each cell, one copy from each parent. Prader–Willi syndrome occurs when the paternal copy is partly or entirely missing. In about 70% of cases, [citation needed] Prader–Willi syndrome occurs when the 15q11-q13 region of the paternal chromosome 15 is deleted. The genes in this region are ...
The doctor reviews the patient's medical records, notices a symptom that his or her colleagues overlooked, performing tests, and finally reaching the correct diagnosis and giving the proper treatment. However, in the case of Prader-Willi syndrome, it is incorrectly said that there is no treatment. This is followed by a brief explanation of why ...
The first imprinted genetic disorders to be described in humans were the reciprocally inherited Prader-Willi syndrome and Angelman syndrome. Both syndromes are associated with loss of the chromosomal region 15q11-13 (band 11 of the long arm of chromosome 15).
