Generation and characterization of a patient-derived iPSC line, CSSi022-A (15666), with a pathogenic MFN2 mutation causing Charcot-Marie-Tooth disease type 2A

Abstract

Charcot-Marie-Tooth disease type 2A (CMT2A; OMIM 609260) is a rare sensorimotor neuropathy caused by mutations in the MFN2 gene (1p36.22). We successfully reprogrammed fibroblasts from an 8-year-old girl carrying a de novo MFN2 mutation into induced pluripotent stem cells using non-integrative vectors. The line shows normal karyotype, pluripotency, and trilineage differentiation, providing a valuable in vitro model to study disease mechanisms.
