Several independent linkage studies have mapped a broad susceptibility region for Alzheimer's disease (AD) on the long arm of chromosome 10. There are several biological candidate genes in this region, including choline acetyltransferase (CHAT). A number of studies have examined the role of CHAT genetic variants with AD risk and age-at-onset (AAO), but the(More)
In addition to genetic effects on disease risk, age-at-onset (AAO) of Alzheimer's disease (AD) is also genetically controlled. Using AAO as a covariate, a linkage signal for AD has been detected on chromosome 14q32 near the alpha1-antichymotrypsin (ACT) gene. Previously, a signal peptide polymorphism (codon -17A>T) in the ACT gene has been suggested to(More)
Linkage studies suggest the presence of putative risk and/or age-at-onset genes for Alzheimer's disease on Chromosome 10. Recently, a genomic converging approach using a combination of linkage, expression and association studies has reported significant associations of the glutathione S-transferase omega 1 and 2 (GSTO1 and GSTO2) genes and possibly the(More)
OBJECTIVE The aim of this study was to examine and describe the topography of the mandibular canal (MC) in both vertical and occlusal dimensions. STUDY DESIGN Fifty-two adult skulls deposited in the University of Pittsburgh School of Dental Medicine skull collection were evaluated in this study. Cone-beam computerized tomographic scans of each skull were(More)
Insulin-degrading enzyme (IDE) is a strong biological and positional candidate gene for Alzheimer's disease (AD). Previously some studies have examined the role of common variation in the IDE gene with AD risk but the results have been inconsistent. In this study we examined the role of 5 SNPs that define a linkage disequilibrium (LD) block spanning 276kb(More)
The gene coding for urokinase-plasminogen activator (PLAU) is a strong biological and positional candidate gene for Alzheimer's disease (AD). Previously some studies have examined the role of common variation in the PLAU gene with AD risk but the results have been inconsistent and this inconsistency could have been due to the use of relatively small sample(More)
