The MitoCharc1 transgene was designed with the human Mitofusin 2 (MNF2) gene driven by a rat enolase (Eno2) promoter. Amino acid 94 of MNF2 was mutated from an Arginine (R) to a Glutamine (Q) to mimic the most commonly mutated residue in Charcot-Marie-Tooth disease type 2A (CMT2A). Line L51 was established.
