Visual Pathway Disease, also known as disorder of visual pathways, is related to louping ill and gait apraxia. An important gene associated with Visual Pathway Disease is CBS (Cystathionine Beta-Synthase), and among its related pathways/superpathways are Peroxisomal lipid metabolism and Pathways of nucleic acid metabolism and innate immune sensing. Affiliated tissues include eye and cortex, and related phenotype is mortality/aging.
