RPTOR and myopathy: It has been reported that loss of Raptor from skeletal muscle leads to a myopathic phenotype, which starts manifesting itself after the postnatal growth period, culminating in premature death between 5–7 months of age.7 In order to understand if also inducible deletion of Raptor from adult skeletal muscle leads to a myopathy at later timepoints, we deleted Raptor from 3‐month‐old mice and analysed muscles after 7 months.
