The CRISPR/Cas9 system and sgRNA 5'-AGACGACATCCCAATAAACA-3' was used to generate the mice. The CRISPR/Cas9 system generated a 1-base pair insertion at c.381_382insT (NM_010694.2). The mutation is predicted to cause a frame-shifted protein product beginning after amino acid 117 of the protein and termination after the inclusion of four aberrant amino acids. (J:274568)
