Cerebral Arteriopathy, Autosomal Dominant, with Subcortical Infarcts and Leukoencephalopathy, Type 2, also known as htra1-related autosomal dominant cerebral small vessel disease, is related to spondylosis and pseudobulbar palsy. An important gene associated with Cerebral Arteriopathy, Autosomal Dominant, with Subcortical Infarcts and Leukoencephalopathy, Type 2 is HTRA1 (HtrA Serine Peptidase 1), and among its related pathways/superpathways are Collagen chain trimerization and Extracellular matrix organization. Affiliated tissues include brain, and related phenotypes are hyperintensity of cerebral white matter on mri and lacunar stroke
