Abstract
Technology of generation of induced pluripotent stem cells followed by differentiation into relevant cell type allows obtaining cell models for studying various inherited human diseases. In the study, an induced pluripotent stem cell (iPSC) line (ICGi046-A) was generated as a result of reprogramming of mononuclear cells of a RASopathy patient carrying pathogenic c.775T>A (p.Ser259Thr) variant in RAF1 to the pluripotent state. The ICGi046-A line demonstrated morphology characteristic of human pluripotent cells, normal karyotype (46,XY), expression of pluripotency markers (OCT4, NANOG, SOX2, TRA-1-60), and capacity to give rise to derivatives of three germ layers during spontaneous differentiation. The iPSC line can be used for studying molecular mechanisms of RASopathies.
