Researchers from The University of Osaka have identified key genetic mutations linked to extracranial arteriovenous malformations (AVMs), a rare and potentially serious vascular disorder. They have revealed that these mutations activate the RAS/RAF/MEK signaling pathway and that the MAP4K4 gene may drive pathological angiogenesis. This may mean that existing cancer drugs that target the same pathway could be effective for AVM treatment, potentially paving the way for novel therapies.
