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]

There are known three molecular causes of Prader–Willi syndrome development. One of them consists in micro-deletions of the chromosome region 15q11–q13. 70% of patients present a 5–7-Mb de novo deletion in the proximal region of the paternal chromosome 15. The second frequent genetic abnormality (~ 25–30% of cases) is maternal ...
Region 15q11-13 is implicated in both Angelman syndrome and Prader–Willi syndrome (PWS). While AS results from mutation, loss or abnormal imprinting involving the UBE3A gene within this region on the maternal chromosome, [17] loss of a different cluster of genes within the same region on the paternal chromosome causes PWS. [19]
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 ...
Urban–Rogers–Meyer syndrome, also known as Prader–Willi habitus, osteopenia, and camptodactyly or Urban syndrome, [1] is an extremely rare inherited congenital disorder first described by Urban et al. (1979).
