Oncogene Linked to Worsening of Blood Vessel Malformations in Brain

Posted by in categories: biotech/medical, genetics, neuroscience

An acquired mutation in the cancer-causing gene PIK3CA can make blood vessel malformations in the brain worse, possibly explaining why these abnormal clusters sometimes rapidly increase in size and cause stroke or seizures, shows new research.


Research from the University of Pennsylvania and Duke University shows an acquired mutation in the cancer-causing gene PIK3CA can trigger uncontrolled growth in cerebral cavernous malformations often leading to strokes or seizures in those affected.
