An important gene associated with Cerebral Arteriopathy, Autosomal Dominant, with Subcortical Infarcts and Leukoencephalopathy, Type 1 is NOTCH3 (Notch Receptor 3), and among its related pathways/superpathways are Signal Transduction and PAK Pathway. The drugs Dabigatran and Donepezil have been mentioned in the context of this disorder. Affiliated tissues include smooth muscle and brain, and related phenotypes are leukoencephalopathy and abnormal cerebral white matter morphology
