Filamin C (FLNC) is a highly important actin crosslinker and multi-adaptor protein in striated skeletal and cardiac muscle. Mutations have been linked to a range of cardiomyopathy types. Here, we generated induced pluripotent stem cells (iPSC) from a patient with dilated cardiomyopathy (DCM) harboring a new, unique heterozygous FLNC mutation p.R2187P. From this patient-specific iPSC line, a corresponding isogenic control line was created by CRISPR/Cas9 genome editing. Both, the patient-specific and isogenic-control iPSC maintained full pluripotency, genomic integrity, and in vitro differentiation capacity. All iPSC lines differentiate into iPSC-cardiomyocytes, hence providing the possibility to study the pathogenesis of FLNC-mediated DCM further.
细丝蛋白 C（FLNC）是一种在横纹骨骼肌和心肌中高度重要的肌动蛋白交联剂和多接头蛋白。突变与多种心肌病类型有关。在这里，我们从一位患有扩张型心肌病（DCM）的患者中生成了诱导多能干细胞（iPSC），该患者携带一种新的、独特的杂合 FLNC 突变 p.R2187P。从这位患者特异性 iPSC 系中，通过 CRISPR/Cas9 基因组编辑创建了一个相应的同基因对照系。患者特异性和同基因对照 iPSC 均保持了完全的多能性、基因组完整性和体外分化能力。所有 iPSC 系均分化为 iPSC-心肌细胞，因此提供了进一步研究 FLNC 介导的 DCM 发病机制的可能性。
