Sequencing of exons 16 and 17 of the β-amyloid precursor protein gene reveals the β-amyloid sequence to be normal in cases of the parkinson dementia complex of guam

Exons 16 and 17 of the β-amyloid precursor protein gene has been sequenced in individuals with the amyotropic lateral sclerosis/Parkinson's dementia complex of Guam to test the hypothesis that this disease is an allelic variant of Alzheimer's disease and to test whether sequence differences within β-amyloid in this population contributes to the non-deposition of this peptide in the disorder. The sequence was normal.
