Whole exome sequencing analysis of intracranial aneurysm in multiplex families from Newfoundland and Labrador
Intracranial aneurysm (IA) is a vascular condition characterized as a saccular dilatation of the cerebral artery wall. The purpose of this study was to identify genetic variants that cause susceptibility to IA in two multiplex families from Newfoundland and Labrador. Whole exome sequencing was compl...
