Parkes Weber Syndrome, also known as parkes-weber syndrome, is related to capillary malformation-arteriovenous malformation 1 and klippel-trenaunay-weber syndrome. An important gene associated with Parkes Weber Syndrome is RASA1 (RAS P21 Protein Activator 1), and among its related pathways/superpathways are Nervous system development and Semaphorin interactions. The drug GTPase-Activating Proteins has been mentioned in the context of this disorder. Affiliated tissues include skin and bone, and related phenotypes are arteriovenous malformation and abnormality of the lower limb
