Summary: COL4A1 Mutation Revealed by an Isolated Brain Hemorrhage

Abstract: Ten to fifteen percent of strokes are related to an intracerebral hemorrhage (ICH). Etiologies are mainly arterial hypertension, amyloid deposition, and vascular malformations. In cases of a young age without vascular risk factors and vascular malformations, a genetic cause has to be suspected, especially a mutation in the gene coding for type IV collagen alpha 1 (COL4A1) [1]. We report a COL4A1 gene mutation in a 45-year-old woman with an isolated ICH in the absence of any other MRI abnormality, which further extends the clinical spectrum of COL4A1 mutations.
