Prader-Willi syndrome and Angelman syndrome are neurogenetic disorders that are caused by the loss of function of imprinted genes in 15q11-q13. Prader-Willi and Angelman syndromes (PWS and AS) typically result from an approximately 4-Mb deletion of human chromosome 15q11-q13, with clustered breakpoints (BP) at either of two proximal sites (BP1 and BP2) and one distal site (BP3).
