High prevalence of pathogenic mutations in patients with early-onset dementia detected by sequence analyses of four different genes
Finckh U, Müller-Thomsen T, Mann U, Eggers C, Marksteiner J, Meins W, Binetti G, Alberici A et al.. American journal of human genetics, 2000-01-01
Topic: Amyloid, tau and blood-test diagnosis
Clinical differential diagnosis of early-onset dementia (EOD) includes familial Alzheimer disease (FAD) and hereditary prion disease. In both disease entities, postmortem brain histopathological examination is essential for unambiguous diagnosis. Mutations in the genes encoding the presenilins (PS1 and PS2) and amyloid precursor protein (APP) are associated with FAD, whereas mutations in the prion protein (PrP) gene are associated with prion disease.

Key findings
- In both disease entities, postmortem brain histopathological examination is essential for unambiguous diagnosis.
- Mutations in the genes encoding the presenilins (PS1 and PS2) and amyloid precursor protein (APP) are associated with FAD, whereas mutations in the prion protein (PrP) gene are associated with prion disease.
- To investigate the proportion of EOD attributable to known genes, we prospectively (i.e., antemortem) screened these four genes for mutations by sequencing genomic PCR products from patients with EOD before age 60 years.
- Family history for dementia was positive (PFH) in 16 patients, negative (NFH) in 17 patients, and unknown (UFH) in 3 patients.
Why it matters
Screening four genes in patients with early-onset dementia found a high prevalence of pathogenic mutations in presenilin, amyloid precursor protein, and prion protein genes. This is a diagnostic and genetic finding and does not provide a treatment, cure, or prevention for Alzheimer's disease.
