755 Mosaic RAS/MAPK variants cause sporadic vascular malformations which respond to targeted therapy

Sporadic vascular malformations (VMs) are complex congenital anomalies of blood vessels which lead to disfigurement, overgrowth, stroke, pain and/or life-threatening bleeding, depending on the vessel size and the body site. Therapeutic options are severely limited and multi-disciplinary management remains challenging. To investigate the pathogenesis of 160 sporadic intracranial and extracranial VMs in which known genetic causes had been excluded, sequencing of affected tissue DNA was undertaken using next generation sequencing optimised for detection of low mutant allele frequency.
