Generation of iPSC lines from CPVT patient carrying heterozygous mutation p.A2254V in the ryanodine receptor 2 gene.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a severe inheritable cardiac disorder, which is characterized by life-threatening cardiac arrhythmias, syncope, seizures, or sudden cardiac death in response to physical exercise or emotional stress. This inherited disease is predominantly caused by mutations in the ryanodine receptor type 2 (RYR2). To minimize the cell line variations for disease modeling, we generated two induced pluripotency stem cell lines (hiPSCs: isCPVTA2254V1-2 and isCPVTA2254V1-3) from skin fibroblasts of one CPVT patient carrying the p.A2254V mutation using CytoTune2.0 Sendai virus cocktail for non-integration reprogramming. All generated iPSCs maintained pluripotency, normal karyotype, and spontaneous in vivo and in vitro differentiation capacity.
