Generation of the iPSC line CUIMCi003-A derived from a patient with severe early onset obesity

Aryl hydrocarbon receptor nuclear translocator 2 (ARNT2) is a basic helix-loop-helix (bHLH/PAS) transcription factor involved in the development of paraventricular nucleus of the hypothalamus (PVH) through the heterodimerization with Single-minded 1 (SIM1) (Michaud et al., 2000). Using a Sendai virus-based approach, the four reprogramming factors OCT3/4, SOX2, KLF4 and C-MYC were delivered into Peripheral Blood Mononuclear Cell (PBMCs) from a 14-year-old girl with early onset obesity carrying a de novo variant (p.P130A) in ARNT2. The resulting iPSC line CUIMCi003-A had a normal karyotype, showed pluripotency and three germ layer differentiation capacity in vitro and was heterozygous for the de novo ARNT2 variant.
