Are You Susceptible to Brain Aneurysms?

(Alexander Stark/ Lab Worldwide) — By studying the genomes of hundreds of thousands of people, scientists from Unige, HUG and the University of Utrecht discovered the genetic basis of intracranial aneurysms.

Nearly three percent of the world’s population is at risk of developing an intracranial aneurysm, a localized dilation of a blood vessel forming a fragile pocket.

Rupture of this aneurysm results in extremely severe, and, in one-third of cases, fatal haemorrhage.

In the framework of the International Stroke Genetics Consortium, a team led by the University of Geneva (Unige), the University Hospitals of Geneva (HUG) and the University of Utrecht is studying the genetic determinants of aneurysms in order to better understand the different forms of the disease and to assess individual risk.
