Generation of JAG1 gene c.1615C > T heterozygous mutation human embryonic stem cell line (SDQLCHe001-A) using cytosine base editor

Pathogenic variants in Jagged-1 (JAG1), which encodes the ligand of the Notch receptor, had been demonstrated to cause Alagille syndrome. However, there is no evidence to support any genotype-phenotype correlations. Here, we generated a gene-edited human embryonic stem cell (hESC) line (H9) carrying the c.1615C > T mutation in JAG1 that was identified in a patient with Alagille syndrome (ALGS). This modified cell line was accomplished by using cytosine base editor (CBE), and may serve as a valuable model for JAG1 mutaion related disease, and facilitate to gain more insight into the biological function of JAG1.
