Somatic RIT1 Delins in Arteriovenous Malformations Hyperactivate RAS-MAPK Signaling Amenable to MEK Inhibition

Academic Background and Problem Statement Arteriovenous Malformations (AVMs) are benign vascular anomalies prone to pain, bleeding, and progressive growth. The primary cause of AVMs is somatic mutations in the RAS-MAPK signaling pathway. However, not all patients have identifiable causative mutations. To further explore the pathogenesis of AVMs, re...
