RESUMO
FHL1 gene locates in the Xq26 region and encodes for four and half LIM domain protein 1. It plays a crucial role in muscle cells and mutations in FHL1 are related to muscular dystrophy (MD). Peripheral blood mononuclear cells (PBMCs) were obtained from 2 family patients with MD that carry a pathogenic missense mutation in FHL1 (c.377G > A, p.C126Y). Induced pluripotent stem cells (iPSCs) were generated by PBMCs reprogramming using the lentiviral-hSTEMCCA-loxP vector, obtaining FHL1-T and FHL1-V iPSCs lines from patients. FHL1 genotype was maintained, and stemness and pluripotency were confirmed in both iPSCs lines.

The arrhythmogenic cardiomyopathy (ACM) is an inherited heart muscle disease characterized by the progressive replacement of contractile myocardium by fibro-fatty adipose tissue, that generates ventricular arrhythmias and sudden death in patients. The ACM has a genetic origin with alterations in desmosomal genes with the most commonly mutated being the PKP2 gene. We generated two CRISPR/Cas9 edited iPSCs lines, one iPSC line with a point mutation in PKP2 reported in patients with ACM and another iPSC line with a premature stop codon to knock-out the same gene.
