CRISPR/Cas9-mediated generation of two isogenic CEP290-mutated iPSC lines

Abstract

CEP290 is an important human disease gene, as mutations are implicated in a broad spectrum of autosomal recessive ciliopathies, including Leber congenital amaurosis and Joubert, Meckel, Senior-LØken or Bardet Biedl syndromes. To create isogenic mutant human induced pluripotent stem cell (hiPSC) lines for disease modeling, we employed CRISPR/Cas9 to introduce disease-relevant mutations into the control hiPSC line HMGU1 (ISFi001-A). Thorough characterization of the lines, including the effect of the mutation at the mRNA and protein level, shows that these CEP290-mutant lines provide a useful resource for studying ciliopathy disease mechanisms and cilia biology through differentiation into diverse cell types and organoids.
