Generation of human induced pluripotent stem cell (iPSC) lines from two patients with BAG3 P209L myofibrillar myopathy-6
Summary
As member of the chaperone-assisted selective autophagy (CASA) complex, BAG3 is important for the turnover of muscle proteins. Patients with a point mutation at position 626 in the BAG3 gene (p.P209L, c.626C>T, Chr.10q26) suffer from polyneuropathy and severe myofibrillar myopathy-6 (MFM6). The latter manifests as skeletal muscle dystrophy and restrictive cardiomyopathy. To model MFM6, we generated two non-isogenic human induced pluripotent stem cell (iPSC) lines from patients with this variant. Pluripotency analyses and germ layer differentiations were performed to check the iPSC quality. These hiPSCs enable the characterization of the pathophysiology of MFM6 and testing of new experimental therapeutic approaches. Copyright © 2025 The Authors. Published by Elsevier B.V.
