The RAB4A gene is a member of the largest group in the Ras superfamily of small GTPases, which regulate membrane trafficking. The encoded protein is associated with early endosomes and is involved in sorting and recycling. In this study, we generated induced pluripotent stem cells (iPSC) from a healthy individual by electroporation of peripheral blood mononuclear cells. We generated a RAB4A homozygous knockout human iPSC line via CRISPR/Cas9 gene editing. The iPSCs-RAB4A-/- had a normal karyotype, expressed pluripotency markers, and maintained trilineage differentiation potential.
