Establishment of a transgene-free iPS cell line (SDQLCHi046-A) from a young patient bearing a HDAC8 mutation and suffering from Cornelia de Lange Syndrome.

In this study, peripheral blood mononuclear cells were isolated from a young male patient bearing a histone deacetyl-lase 8 (HDAC8) mutation and suffering from Cornelia de Lange Syndrome verified by clinical and genetic diagnosis. Induced pluripotent stem cells (iPSCs) were established by a non-integrative method, using plasmids carrying OCT4, SOX2, KLF4, BCL-XL and C-MYC. The established iPSCs presented typical pluripotent cells morphology, and expressed pluripotent stem cell markers at the mRNA and protein level. The iPSCs also showed differentiative capacity in vitro, and a normal karyotype. In addition, the established iPSCs still carried the HDAC8 mutation observed in the donor tissue.
