• This transgenic expression of wildtype human MTRFR partially rescues the embryonic lethality caused by homozygosity of the K155* mutation in that some homozygotes were born although less than half the number expected from a full rescue. Surviving homozygotes were found to be normal in all assessments including body weight, wire hang duration, sciatic nerve conduction velocity, peripheral nerve histology, retina, optic nerve, ratio of triceps surae weight to body weight, and no biomarker indication of integrated stress response.
