The serendipitous onset of B-ALL in a patient affected by the germinal Notch mutation-dependent Alagille syndrome allowed us to establish a B-ALL cell line (VR-ALL) bearing a genetic loss of function in components of Notch signaling. Exome sequencing revealed deleterious mutations in some components of Notch signaling. In addition, VR-ALL is sensitive both in vitro and in vivo to ?-secretase inhibitors (GSIs) as well as conventional anti-leukemic drugs.
