Fig. 1From: Germline activating MTOR mutation arising through gonadal mosaicism in two brothers with megalencephaly and neurodevelopmental abnormalitiesSimplified representation of the MTOR signaling network. Green arrows indicate the specific substrates shown to be phosphorylated/over-stimulated by p.E1799K-hyperactivated MTOR kinase.
