The dynamin-1-like protein (DNM1L), also termed DRP1, is essential for mitochondrial fission. Mutations in DNM1L are associated with neurological disorders and cardiac dysfunction. To decipher the role of DNM1L in human induced pluripotent stem cells (hiPSCs) and in their differentiated counterparts, we used CRISPR/Cpf1 and generated a human iPSC line with a mutation by targeting exon 18 of the DNM1L gene. The generated compound heterozygous (biallelic) DNM1L mutant cell line showed normal cell morphology, genomic stability, and expression of classical stem cell markers. Furthermore, the cells can be differentiated efficiently into the three germ layers meso-, endo-, and ectoderm.
