Incidence and Impact of Activating Mutations of the RAS-RAF-MEK-ERK Pathway in Patients with Philadelphia-Negative (Ph-negative) Myeloproliferative Neoplasms (MPNs) and Myelodysplastic/Myeloproliferative Disorders–Unclassified (MDS/MPD-U)
Abstract:Introduction: Mutations that activate the RAS-RAF-MEK-ERK pathway have long been known to occur in patients with solid tumors and hematological malignancies. The most common mutations occur in the Ras family of GTPases (HRAS, NRAS, KRAS) and the Raf family of serine-threonine kinases (ARAF, BRAF, CRAF). In myeloid malignancies, RAS mutations have mainly been described in patients with acute myeloid leukemia, chronic myelomonocytic leukemia (CMML) and myelodysplastic syndrome. There are few studies describing t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
