Key result
Induced pluripotent stem cells (RCPCMi011-A) were successfully generated from fibroblasts of a male patient with FLNC-associated restrictive cardiomyopathy and confirmed to be pluripotent.
Why the study?
To study the pathogenetic mechanisms of FLNC-associated restrictive cardiomyopathy at the cellular level.
The successful derivation of the RCPCMi011-A iPSC line provides a valuable in vitro model for studying the cellular mechanisms of FLNC-associated restrictive cardiomyopathy.
Does not alter RCM management; extends cellular mechanisms of FLNC mutations but leaves clinical translation open.
Restrictive cardiomyopathy (RCM) is an orphan heart disease, which is characterized by an increase in myocardial stiffness and restriction of ventricular filling with blood in the diastole. Familial forms of RCM are associated with mutations in genes encoding sarcomeric and cytoskeletal proteins. One of them is the FLNC gene encoding the actin-binding protein of Z-disks filamin C (Brodehl et al., 2016). To study the pathogenetic mechanisms of FLNC-associated RCM at the cellular level, the authors generated iPSCs (RCPCMi011-A) from fibroblasts of a patient with RCM caused by the c.7416_7418delGAA/p.Glu2472_Asn2473delAsp mutation in the FLNC gene. The pluripotent state of RCPCMi011-A iPSCs was confirmed by typical stem cell morphology, normal male karyotype maintenance, expression of pluripotency markers, and the ability to differentiate into three germ layers.

Goliusova et al. (2024) studied Restrictive cardiomyopathy (RCM) (n=1). Generation of iPSCs (RCPCMi011-A) was evaluated on Confirmation of pluripotent state. Induced pluripotent stem cells (RCPCMi011-A) were successfully generated from fibroblasts of a male patient with FLNC-associated restrictive cardiomyopathy and confirmed to be pluripotent.
