Defects in rat sarcoma viral oncogene homolog (RAS)-extracellular signal regulated kinase (ERK) and phosphatidylinositol 3-kinase (PI3K)-mammalian target of rapamycin (MTOR) signaling pathways have recently been shown to cause several genetic disorders classified as neuro-cardio-facial-cutaneous (NCFC) and Hamartoma syndromes. Although these pathways are well-known players in cell proliferation and cancer, their role in cognitive function is less appreciated. Here, we focus on the cognitive problems associated with mutations in the RAS-ERK and PI3K-MTOR signaling pathways and on the underlying mechanisms revealed by recent animal studies. Cancer drugs have been shown to reverse the cognitive deficits in mouse models of NCFC and Hamartoma syndromes, raising hopes for clinical trials.
