Novel amyloid precursor protein mutation in an Iowa family with dementia and severe cerebral amyloid angiopathy

Abstract excerpt

Several mutations in the amyloid precursor protein (APP) gene have been found to associate with pathologic deposition of the beta-amyloid peptide (Abeta) in neuritic plaques or in the walls of cerebral vessels. We report a mutation at a novel site in APP in a three-generation Iowa family with autosomal dominant dementia beginning in the sixth or seventh decade of life.
