Ruptured intracranial aneurysm(IA)leads to aneurysmal subarachnoid hemorrhage(aSAH), which is the most severe type of stroke. Besides age, sex, and alcohol consumption, family history is considered an important risk factor. Approximately 5% of the Japanese population is affected by unruptured cerebral aneurysms. However, their developmental processes and pathologies remain unclear. Familial cerebral aneurysms account for 10% of all cerebral aneurysm cases, and somatic gene mutations are believed to be involved in their development. This review summarizes the recent findings from family-based, genome-wide association, sequencing, and somatic gene mutation studies on IA.
