Objective
Several hereditary ischemic small‐vessel diseases of the brain have been reported during the last decade. Some of them have ophthalmological, mainly retinal, manifestations. Herein, we report on a family affected by vascular leukoencephalopathy and variable abnormalities of the anterior chamber of the eye.
Methods
After the occurrence of a small, deep infarct associated with white matter lesions in a patient with a medical history of congenital cataract and amblyopia, we conducted clinical and neuroradiological investigations in 10 of her relatives.
Results
Diffuse leukoencephalopathy associated with ocular malformations of the Axenfeld–Rieger type was observed in five individuals. Familial genetic analyses led to the identification of a novel missense mutation in the COL4A1 gene, p.G720D, which cosegregates with the disease.
Interpretation
Our data corroborate previous observations demonstrating the role of COL4A1 in cerebral microangiopathy and expand the phenotypic spectrum associated with mutations in this gene. We delineate a novel association between the Axenfeld–Rieger anomaly and leukoencephalopathy and stroke. Ann Neurol 2007
