Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an arrhythmia syndrome characterized by adrenaline induced ventricular tachycardia. The primary genetic aetiologies underlying CPVT are either autosomal dominant or autosomal recessive inheritance,resulting from heterozygous mutations in cardiac ryanodine receptor (RYR2) and homozygous mutations in cardiac calsequestrin-2 (CASQ2),respectively. Recently,a large family with autosomal dominant CPVT due to a heterozygous mutation in CASQ2,p.Lys180Arg,was reported. This resource is the first induced pluripotent stem cell line generated from a patient with autosomal dominant CPVT due to a heterozygous mutation in CASQ2. Induced pluripotent stem cells were generated from the whole blood of a 40-year-old woman with severe CPVT who is heterozygous for the p.Lys180Arg CASQ2 mutation. Induced pluripotent stem cell (iPSC) characterization confirmed expression of pluripotency makers,trilineage differentiation potential,and the absence of exogenous pluripotency vector expression.

Hypertrophic cardiomyopathy (HCM) is an inherited cardiomyopathy characterized by left ventricular hypertrophy ≥15 mm in the absence of loading conditions. HCM has a prevalence of up to one in 200,and can result in significant adverse outcomes including heart failure and sudden cardiac death. An induced pluripotent stem cell (iPSC) line was generated from peripheral blood mononuclear cells obtained from the whole blood of a 38-year-old female patient with HCM in which genetic testing identified the well-known pathogenic p.Arg403Gln mutation in myosin heavy chain 7. iPSCs express pluripotency markers,demonstrate trilineage differentiation capacity,and display a normal 46,XX female karyotype. This resource will allow further assessment of the pathophysiological development of HCM. View Publication
