Germline Mutations in Components of the Ras Signaling Pathway in Noonan Syndrome and Related Disorders

Abstract excerpt

Ras proteins control a variety of critical cellular processes, and somatic mutations in RAS genes (and other members of signaling networks regulated by Ras) are common in human malignancies. Ras proteins are guanosine triphosphate (GTP)-binding proteins that cycle between active GTP-bound and inactive guanosine diphosphate (GDP) bound conformations. Cancer-associated Ras mutations typically alter amino acids G12,...
