MTOR (P42345) variants and mutations

MTOR (also known as P42345) is a human protein-coding gene encoding a serine/threonine-protein kinase protein. It integrates nutrient, energy, oxygen, and growth-factor signals to control protein synthesis, autophagy, metabolism, and cell growth. Activating germline or mosaic variants can cause developmental brain overgrowth and epilepsy, while persistent pathway activation is common in cancer. This analysis covers 5,679 MTOR variants and mutations. Of these, 56% have computational variant effect predictions. Disease context includes Macrocephaly-intellectual disability-neurodevelopmental disorder-small thorax sy, isolated focal cortical dysplasia type II, and overgrowth syndrome and/or cerebral malformations due to abnormalities in MTOR p. Example MTOR variants include L2V, G3E, and G3R.
