Retinal vasculopathy with cerebral leukodystrophy is an adult-onset autosomal dominant disorder involving the microvessels of the brain and resulting in central nervous system degeneration with progressive loss of vision, stroke, motor impairment, and cognitive decline. Death occurs in most patients 5 to 10 years after onset. A subset of affected individuals have systemic vascular involvement evidenced by Raynaud's phenomenon, micronodular cirrhosis, and glomerular dysfunction. [From OMIM]
