Imprinting on human chromosome 15q11-q13 is controlled by a bipartite imprinting center
(IC) that maps to the SNRPN locus. Deletions of the IC result in an imprinting defect and
Prader-Willi syndrome or Angelman syndrome (AS). We have now identified a 5-kb IC
deletion in an English AS patient (AS-LO); this represents the smallest microdeletion found
in AS and narrows down the shortest region of deletion overlap to 880 bp.
Abstract
Imprinting on human chromosome 15q11-q13 is controlled by a bipartite imprinting center (IC) that maps to the SNRPN locus. Deletions of the IC result in an imprinting defect and Prader-Willi syndrome or Angelman syndrome (AS). We have now identified a 5-kb IC deletion in an English AS patient (AS-LO); this represents the smallest microdeletion found in AS and narrows down the shortest region of deletion overlap to 880 bp.
