title: The C3-F gene in patients with intracranial saccular aneurysms.
abstract: The C3-F gene has previously been found associated with atherosclerotic vascular diseases. The occurrence of the C3-F gene was therefore investigated in a group of 110 hospitalized patients with intracranial saccular aneurysms. The C3-F gene occurred equally often in patients and controls. In patients with a ruptured aneurysm, however, the C3-F gene frequency was significantly increased in subjects aged 40-49 years followed by a marked and statistically significant decline with increasing age. The findings suggest that the C3-F gene may be a risk factor for early aneurysm rupture.
