APP (Amyloid-beta precursor protein) variants and mutations

APP (also known as Amyloid-beta precursor protein) is a human protein-coding gene encoding an amyloid-beta precursor protein. Its processing produces multiple fragments involved in neuronal biology, including amyloid-beta peptides generated by beta- and gamma-secretase cleavage. Increased amyloidogenic processing, pathogenic variants, or increased gene dosage can cause autosomal dominant Alzheimer disease or cerebral amyloid angiopathy. This analysis covers 1,078 APP variants and mutations. Of these, 76% have computational variant effect predictions. Disease context includes Alzheimer disease, Alzheimer disease type 1, and cerebral amyloid angiopathy, APP-related. Example APP variants include P3H, L5F, and L5V.
