A new study shows that some cases of early-onset Alzheimer disease result from duplications of the APP locus, which encodes the amyloid β precursor protein. This finding fulfills a 20-year-old prediction that genetic variability in APP expression could lead to disease and provides further, perhaps definitive, evidence for the amyloid hypothesis of the disorder.
