Engineering of targeted megabase-scale deletions in human induced pluripotent stem cells.

ABSTRACT: Recurrent chromosomal deletions spanning several megabases are often found in hematological malignancies. The ability to engineer deletions in model systems to functionally study their effects on the phenotype would enable, first, determination of whether a given deletion is pathogenic or neutral and, second, identification of the critical genes. Incomplete synteny makes modeling of deletions of megabase scale challenging or impossible in the mouse or other model organisms. Furthermore, despite the breakthroughs in targeted nuclease technologies in recent years, engineering of megabase-scale deletions remains challenging and has not been achieved in normal diploid human cells. Large deletions of the long arm of chromosome 7 (chr7q) occur frequently in myelodysplastic syndrome (MDS) and are
