Science, 1987•science.orgThe amyloid β protein has been identified as an important component of both
cerebrovascular amyloid and amyloid plaques of Alzheimer's disease and Down syndrome.
A complementary DNA for the β protein suggests that it derives from a larger protein
expressed in a variety of tissues. Overexpression of the gene in brain tissue from fetuses
with Down syndrome (trisomy 21) can be explained by dosage since the locus encoding the
β protein maps to chromosome 21. Regional localization of this gene by both physical and …

The amyloid β protein has been identified as an important component of both cerebrovascular amyloid and amyloid plaques of Alzheimer's disease and Down syndrome. A complementary DNA for the β protein suggests that it derives from a larger protein expressed in a variety of tissues. Overexpression of the gene in brain tissue from fetuses with Down syndrome (trisomy 21) can be explained by dosage since the locus encoding the β protein maps to chromosome 21. Regional localization of this gene by both physical and genetic mapping places it in the vicinity of the genetic defect causing the inherited form of Alzheimer's disease.
