Novel Factor XIII variant identified through whole-genome sequencing in a child with intracranial hemorrhage.

Pediatric stroke can be either hemorrhagic or ischemic, with ∼5% of hemorrhagic strokes being caused by genetic coagulopathies. We report an 8 mo old presenting with a hemorrhagic stroke caused by severe Factor XIII deficiency (OMIM # 613225) in whom rapid whole-genome sequencing identified a novel variant in the F13A1 gene c.1352_1353delAT (p.His451ArgfsTer29).
