Abstract
Parkinson’s disease is a neurodegenerative disease, and genetic variants are known in only 5% of cases. Analysis of clinical exome of a patient with a family history of Parkinsonism revealed polymorphisms in the LRRK2 and PINK1 genes. The patient’s mononuclear blood cells are reprogrammed to a pluripotent state using episomal vectors expressing pluripotency factors. The line of induced pluripotent stem cells (iPSCs) demonstrated the typical morphology of human pluripotent cells, had a normal karyotype, expressed OCT4, NANOG, SOX2, and TRA-1-60 and gave derivatives of three germ layers during spontaneous differentiation in vitro. The resulting iPSCs line is a valuable tool for studying the contribution of polymorphic variants of the LRRK2 and PINK1 genes to the pathogenesis of Parkinson’s disease.
