Abstract

Previous research has hypothesized an association between Alzheimer's disease and the amyloid precursor protein (APP) gene found on chromosome 21. We report the case of a 78-year-old woman with Down's syndrome with partial trisomy 21 [46,XX,rec(21)dup q, inv(21) (p12q22.1)]. No evidence of Alzheimer's disease was found on neuropsychological, magnetic resonance imaging, and neuropathological assessment. The gene sequence for APP was present in only two copies. This case further supports the hypothesis that Alzheimer's disease is associated with trisomy for proximal chromosome 21q, including the APP gene.
