Generation of an induced pluripotent stem cell line (MUSIi015-A) from a diabetic patient carrying mutations in ZYG11A (p.L475P) and GATA6 (p.E51K).

Two heterozygous mutations (p.L475P in ZYG11A and p.E51K in GATA6) were identified in a family with autosomal dominant diabetes. ZYG11A-p.L475P was proposed as a causative mutation because of the complete segregation with hyperglycemia and the proven pathogenic effect on beta-cell expansion. The modifying effect of GATA6-p.E51K was proposed owing to the earlier onset of the carriers. Herein, we establish a line of induced pluripotent stem cells (iPSCs) from peripheral blood mononuclear cells (PBMCs) of a proband who carries both mutations using Sendai viral vectors. The generated iPSC line was characterized for pluripotency, chromosomal normality, and authentication.

Generation of an induced pluripotent stem cell line (MUSIi014-A) from an affected member of a family with autosomal dominant diabetes carrying p.L475P mutation in ZYG11A gene associated with a cell cycle arrest in beta-cell.

A heterozygous mutation (c.T1424C: p.L475P) in ZYG11A completely segregating with hyperglycemia in a Thai family with familial diabetes of the adulthood has been reported as a cause of cell cycle arrest in 1.1B4 cell line. This mutation is a suggestive cause of failure in adaptive beta-cell expansion which, thereby, contributes to the development of diabetes in the family. Here, an induced pluripotent stem cell (iPSC) line from peripheral blood mononuclear cells (PBMCs) of an affected family member carrying the mutation was generated using Sendai viral reprogramming. The established iPSC line is characterized and confirmed for pluripotency and chromosomal integrity.
