- What causes Prader-Willi syndrome (PWS)? - NICHD
Prader-Willi syndrome is caused by genetic changes on an "unstable" region of chromosome 15 that affects the regulation of gene expression, or how genes turn on and off This part of the chromosome is called unstable because it is prone to being shuffled around by the cell's genetic machinery before the chromosome is passed on from parent to child

- Other Prader-Willi Syndrome (PWS) FAQs - NICHD
Angelman syndrome, like PWS, results from defects in one region of chromosome 15 The two syndromes both involve missing or silenced genes in this region, called the Prader-Willi critical region (PWCR) This section of the chromosome is "imprinted," and the genes involved in Angelman syndrome and PWS have different sex-specific imprinting patterns
- How do healthcare providers diagnose Prader-Willi syndrome (PWS . . . - NICHD
In many cases of Prader-Willi syndrome, diagnosis is prompted by physical symptoms in the newborn If a newborn is unable to suck or feed for a few days and has a "floppy" body and weak muscle tone, a health care provider may conduct genetic testing for Prader-Willi syndrome 1,2,3 Formal diagnostic criteria for recognizing Prader-Willi syndrome depend on the age of the individual-specifically
