“…Genome engineering has been used to model monogenic diabetes by knocking out genes critical for pancreatic and β cell development in hPSCs (PDX1, NEUROG3, ARX, GLIS3, NEUROD1) (reviewed in [ 57 , 58 ]). Correcting mutations in patient-derived iPSCs has led to a better understanding of disease mechanisms in rare cases of neonatal diabetes [ [59] , [60] , [61] ].…”
