A Novel COL4A2 Mutation Associated with Recurrent Strokes

Daryl C. McHugh, Charles Esenwa

Research output: Contribution to journalArticlepeer-review


Mutations in type four collagens, specifically COL4A1 and COL4A2, have been associated with cerebral small vessel disease (SVD), defined as lacunar infarcts, deep intracerebral hemorrhages (ICH), and leukoaraiosis. We present a case of a man with recurrent cerebral infarcts, related to a novel COL4A2 mutation, the p.A1534S variant. Magnetic resonance imaging demonstrated multiple lacunar infarcts, numerous deep and lobar microhemorrhages and advanced leukoaraiosis. Evaluation for COL4A2 mutations should be considered when suspecting a genetic cerebral small vessel disease.
