To critically evaluate NF1 mutational equivalency in human brain cells, Anastasaki and colleagues generated an isogenic series of seven human induced pluripotent stem cell lines harboring different NF1 patient NF1 mutations. Although all mutations increased 2D NPC and astrocyte RAS activity and cell proliferation, distinct NF1 mutations had differential effects on NPC proliferation, apoptosis and neuronal differentiation within 3D cerebral organoids.
