Abstract

Mutations at codon 717 in exon 17 of the beta-amyloid precursor protein (APP) gene have previously been shown to segregate with early onset Alzheimer's disease in some families. We have identified a double mutation at codons 670 and 671 (APP 770 transcript) in exon 16 which co-segregates with the disease in two large (probably related) early-onset Alzheimer's disease families from Sweden. Two base pair transversions (G to T, A to C) from the normal sequence predict Lys to Asn and Met to Leu amino acid substitutions at codons 670 and 671 of the APP transcript. This mutation occurs at the amino terminal of beta-amyloid and may be pathogenic because it occurs at or close to the endosomal/lysosomal cleavage site of the molecule. Thus, pathogenic mutations in APP frame the beta-amyloid sequence.

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.
