A MUTATION at codon 717 of the β-amyloid precursor protein gene has been found to cosegregate with familial Alzheimer's disease in a single family1. This mutation has been reported in a further five out of ∼ 100 families multiply affected by Alzheimer's disease1–4. We have identified another family, F19, in which we have detected linkage between the β-amyloid precursor protein gene and Alzheimer's disease. Direct sequencing of exon 17 (ref. 5) in affected individuals from this family has… 
Mutation in codon 713 of the β amyloid precursor protein gene presenting with schizophrenia
A single abnormal case is identified — a chronic schizophrenic with cognitive defects — and the position of the mutation in a critical portion of the APP gene suggests that it may well prove to be pathogenic.
Mutation of the β-amyloid precursor protein in familial Alzheimer's disease increases β-protein production
C cultured cells which express a β-APP complementary DNA bearing a double mutation found in a Swedish FAD family produce ∼6–8-fold more Aβ than cells expressing normalβ-APP, and this increase is confirmed for elucidating the fundamental mechanism of Alzheimer's disease.
A pathogenic mutation for probable Alzheimer's disease in the APP gene at the N–terminus of β–amyloid
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 is identified.
Screening for mutations at codon 717 of the amyloid precursor protein gene in Alzheimer's disease
Abstract Three kinds of missense mutation at codon 717 of amyloid precursor protein (APP) gene (Val→Ile; Val→Gly; Val→Phe) were screened in 114 patients with familial and sporadic Alzheimer's disease
Novel amyloid precursor protein gene mutation (codon 665Asp) in a patient with late‐onset Alzheimer's disease
A novel point mutation, substitution of cytosine for guanine, is found at nucleotide 2119 (amyloid precursor protein 770 messenger RNA transcript) in a patient with late‐onset Alzheimer's disease, and the BglII restriction fragment length polymorphism enables investigators to determine the frequency of this polymorphism in normal subjects and Alzheimer's patients.
Cloning of a gene bearing missense mutations in early-onset familial Alzheimer's disease
A minimal cosegregating region containing the AD3 gene is defined, and at least 19 different transcripts encoded within this region corresponds to a novel gene whose product is predicted to contain multiple transmembrane domains and resembles an integral membrane protein.
Amyloid precursor protein gene mutations responsible for early-onset autosomal dominant Alzheimer's disease.
All APP mutations have been summarised and their molecular effects on the APP metabolism have been discussed.


A mutation in the amyloid precursor protein associated with hereditary Alzheimer's disease.
Direct sequencing of DNA from a family with autopsy-proven Alzheimer's disease revealed a single amino acid substitution (Phe for Val) in the transmembrane domain of the amyloid precursor protein, which may be the inherited factor causing both amyloids fibril formation and dementia.
Segregation of a missense mutation in the amyloid precursor protein gene with familial Alzheimer's disease
It is demonstrated that in this kindred, which shows linkage to chromosome 21 markers, there is a point mutation in the APP gene that causes an amino-acid substitution close to the carboxy terminus of the β-amyloid peptide.
Mutation of the Alzheimer's disease amyloid gene in hereditary cerebral hemorrhage, Dutch type.
Cloning and sequencing of the two exons that encode the amyloid protein from two patients with this amyloidsosis revealed a cytosine-to-guanine transversion, a mutation that caused a single amino acid substitution (glutamine instead of glutamic acid) at position 22 of the ameloid protein.
Amyloid A4 protein and its precursor in Down's syndrome and Alzheimer's disease.
Immunocytochemical studies of brain tissue from 26 patients with Down's syndrome showed that the deposition of A4 protein amyloid began in these patients approximately 50 years earlier than it began in 127 normal aging subjects studied previously, although the rate of deposition was the same.
Amyloid plaque core protein in Alzheimer disease and Down syndrome.
The shared 4-kDa subunit indicates a common origin for the amyloids of the plaque core and of the congophilic angiopathy of Alzheimer disease and Down syndrome.
Cleavage of amyloid beta peptide during constitutive processing of its precursor.
Direct protein structural analyses showed that constitutive processing in human embryonic kidney 293 cells cleaves APP in the interior of the A Beta P, thus preventing A beta P deposition.
