Alzheimer's Disease 1, also known as alzheimer disease type 1, is related to early-onset autosomal dominant alzheimer disease and mild cognitive impairment. An important gene associated with Alzheimer's Disease 1 is APP (Amyloid Beta Precursor Protein), and among its related pathways/superpathways are Neuroscience and A-beta Plaque Formation and APP Metabolism. Affiliated tissues include brain and endothelial, and related phenotypes are homeostasis/metabolism and growth/size/body region
