Generation of human induced pluripotent stem cell lines derived from four DiGeorge syndrome patients with 22q11.2 deletion

DiGeorge syndrome (22q11.2 deletion syndrome, or CATCH22 syndrome), caused by hemizygous deletion of chromosome 22q11.2, results in the poor development of multiple organs. Here we have generated DiGeorge syndrome-specific human induced pluripotsnt stem cells (hiPSCs) derived from four patients. These established hiPSC lines showed self-renewal and pluripotency and carried a hemizygous deletion in 22q11.2. Since the molecular pathogenesis of DiGeorge syndrome caused by the 22q11.2 deletion is largely unknown, these cell resources will be useful for recapitulating disease phenotypes and for developing new therapies for DiGeorge syndrome.
