▶Extreme cerebrospinal fluid amyloid β levels identify family with late‐onset Alzheimer's disease presenilin 1 mutationReviewJohn S. K. Kauwe et al.(2007)· Annals of Neurology
A review of genetic discoveries in Alzheimer's disease using cerebrospinal fluid (CSF) levels of amyloid-beta 42 (Aβ42) and phosphorylated tau (pTau181) as endophenotypes. The paper discusses multiple GWAS and sequencing studies that identified novel AD risk variants including rs9877502 (3q28, p=4.89×10⁻⁹), rs514716 in GLIS3 (p=1.07×10⁻⁸), and rs6922617 in TREM cluster (p=3.58×10⁻⁸), as well as functional characterization of known AD variants including APOE, MAPT, and TREM2. The review emphasizes the increased statistical power of using quantitative CSF biomarkers compared to traditional case-control designs.
About APOE
The protein encoded by this gene is a major apoprotein of the chylomicron. It binds to a specific liver and peripheral cell receptor, and is essential for the normal catabolism of triglyceride-rich lipoprotein constituents. This gene maps to chromosome 19 in a cluster with the related apolipoprotein C1 and C2 genes. Mutations in this gene result in familial dysbetalipoproteinemia, or type III hyperlipoproteinemia (HLP III), in which increased plasma cholesterol and triglycerides are the consequence of impaired clearance of chylomicron and VLDL remnants.
