Abstract

A mutation at codon 717 of the beta-amyloid precursor protein gene has been found to cosegregate with familial Alzheimer's disease in a single family. This mutation has been reported in a further five out of approximately 100 families multiply affected by Alzheimer's disease. We have identified another family, F19, in which we have detected linkage between the beta-amyloid precursor protein gene and Alzheimer's disease. Direct sequencing of exon 17 in affected individuals from this family has revealed a base change producing a Val----Gly substitution, also at codon 717. The occurrence of a second allelic variant at codon 717 linked to the Alzheimer's phenotype supports the hypothesis that they are pathogenic mutations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
