Generation of a human induced pluripotent stem cell (iPSC) line from a patient carrying a P33T mutation in the PDX1 gene

Homozygous loss-of-function mutations in the gene coding for the homeobox transcription factor PDX1 leads to pancreatic agenesis, whereas certain heterozygous point mutations are associated with Maturity-Onset Diabetes of the Young 4 (MODY4) and Type 2 Diabetes Mellitus (T2DM). To understand the pathomechanism of MODY4 and T2DM, we have generated iPSCs from a woman with a P33T heterozygous mutation in the transactivation domain of PDX1. The resulting PDX1 P33T iPSCs generated by episomal reprogramming are integration-free, have a normal karyotype and are pluripotent in vitro and in vivo. Taken together, this iPSC line will be useful to study diabetes pathomechanisms.
