Prader–Willi syndrome (i; abbreviated P.W.S) is a rare genetic disorder in which seven genes (or some subset thereof) on chromosome 15 (q 11–13) are deleted or unexpressed (chromosome 15q partial deletion) on the paternal chromosome. It was first described in 1956 by Andrea Prader (1919–2001), Heinrich Willi (1900–1971), Alexis Labhart (19...

Syndrome in which there is an absence of paternal chromosome 15q11q13. Short stature, obesity and mild mental retardation are features of the syndrome. Uniparental disomy leads to differences between this and Angelman syndrome where it is the equivalent maternal region that is deleted. See imprinting.
