Here, we generated a biallelic mutation in the TLE1 (Transducin Like Enhancer of Split 1) gene using CRISPR-Cas9 editing in the human embryonic stem cell (hESC) line WA01. The homozygous knockout cell line, TLE1-464-G04, displays loss of TLE1 protein expression while maintaining pluripotency, differentiation potential and genomic integrity.
