Abstract
The search for new polymorphisms associated with hereditary diseases is important for diagnostics and the study of the disease’s development pathology. The authors have analyzed a clinical exome of a Parkinson’s disease patient and identified single-nucleotide variations in the LRRK2 (c.1000G>A, c.2167A>G) and PINK1 (c.1562A>C) genes. The LRRK2:c.1000G>A mutation has uncertain clinical significance and is interesting for further investigation. We generated induced pluripotent stem cells (iPSCs) from peripheral blood mononuclear cells (PBMCs) of the patient by nonintegrating episomal vectors. iPSCs demonstrate typical morphology and normal karyotype (46,XY), express pluripotency markers (OCT4, SOX2, NANOG, SSEA4, TRA-1-60), and are able to produce derivatives of three germ layers.
