Generation of human induced pluripotent stem cell line derived from dilated cardiomyopathy with compound heterozygous TTN and TAB2 variants

Dilated cardiomyopathy (DCM) represents the most prevalent form of cardiomyopathy. Multiple genetic variants are linked to DCM severity. We have established a human induced pluripotent stem cell (iPSC) line derived from a DCM patient harboring the p.M17164T (c.51491T>C) and p.Y138C (c.413A>G) mutations in the Titin (TTN) gene, as well as the p.Q3_S5del (c.9_17del) deletion in the TAB2 gene. The established iPSCs exhibited a normal karyotype (46, XX) and expressed pluripotency markers, successfully differentiating into cardiomyocytes. This cell line serves as a valuable resource for investigating the pathogenic mechanisms underlying DCM associated with TTN and TAB2 variants.
