Abstract
Skin fibroblasts from a patient with intellectual disability and ring chromosome 22 were reprogrammed into induced pluripotent stem cells (iPSCs) to establish a clonal stem cell lines, IMGTi001-A (iTAF5-29) and IMGTi001-B (iTAF5-32). Because of ring chromosome mitotic instability these cell lines show mosaic karyotypes with 46,XX,r(22) in >83% cells, 45,XX,-22 as minor class and sporadically cells with other karyotypes. Differentiation in derivatives of all three germ layers was shown in teratoma assay for IMGTi001-A, and in embryoid bodies for both cell lines. To our knowledge, human iPSC lines with ring chromosome are described for the first time.
