Popis: Truncating variants in TTN (TTNtv) are present in 15–25 % of patients with idiopathic dilated cardiomyopathy. Interestingly, the pathogenicity of TTNtv seems to be linked to their location within the gene. More proximal I-band TTNtv (TTNtvI) harbour less pathogenic potential than distant A-band TTNtv (TTNtvA). We created isogenic human induced pluripotent stem cell lines (hiPSC) with TTNtvI and TTNtvA using CRISPR/Cas9, for the investigation of the pathomechanism in hiPSC-derived cardiomyocytes (hiPSC-CMs). Exon 48 (E48), located in the I-band, and exon 357 (E357), located in the A-band were targeted.
