Generation of an Induced Pluripotent Stem Cell Line, ICGi043-A, by Reprogramming Peripheral Blood Mononuclear Cells from a Parkinson’s Disease Patient with p.G2019S Mutation in the LRRK2 Gene

The pathological variant p.G2019S in the LRRK2 gene leads to the occurrence of a hereditary form of Parkinson’s disease (PD) and affects 7% of patients with a familial form of the disease. However, the mechanisms that trigger pathological events during the development of the disease are not yet fully understood. The authors obtained iPSCs (ICGi043-A line) from peripheral blood mononuclear cells of a patient with a hereditary form of PD associated with the genetic variant c.6055G>A (p.G2019S, rs34637584) in the LRRK2 gene using transfection with episomal vectors. iPSCs rapidly proliferate in dense monolayer cell colonies, are positive for endogenous alkaline phosphatase, have a normal karyotype (46,XX), express pluripotency markers (OCT4, SOX2, NANOG, TRA-1-60, SSEA-4), and are capable to differentiate into three germ layers (ecto-, endo-, and mesoderm), which confirms their pluripotent status. Future directed differentiation of the obtained iPSCs into dopaminergic neurons will allow the creation of an in vitro cell model of PD associated with the pathological variant c.6055G>A in the LRRK2 gene and contribute to understanding the pathogenesis of PD.
