One third of patients die from hemorrhage and another third have severe permanent disability. Genetic factors are crucial in the formation and clinical evolution of aneurysms. Multiple loci have been associated with the development of intracranial aneurysms, many of them involve multiple pathways related to the maintenance of vascular endothelium and extracellular matrix integrity. The objective of our study is to characterize whether polymorphisms in genes involved in the maintenance of the vascular endothelium could modify the risk of developing aneurysms, presenting a subarachnoid hemorrhage and its clinical complications.
