Where this comes from

Abstract

We report four children with idiopathic stroke syndromes who were assayed for human leukocyte antigen (HLA) class I markers and found to have HLA-B51 in common. This finding suggests that there may be a genetic predisposition for "idiopathic" childhood stroke, and host factors, possibly in concert with environmental factors or viruses, may play a major role in the mechanism of unexplained occlusion of the cerebral vasculature in children.
