Vascular malformations in the brains of Ccm2Gt(RRG051)Byg/Ccm2+ mice

cardiovascular system
abnormal brain vasculature morphology ( J:105314 )
• develop cerebral vascular malformations, including hemorrhaging, at low penetrance; clusters of blood vessels are similar to small cavernous malformations or capillary telangiectasias
intracranial hemorrhage ( J:105314 )
• low penetrance

nervous system
