Linkage regions are reproduced from Bertram and Tanzi [6]. Transcripts differentially expressed (DE) between non-demented and AD subjects (hypothesis I) were compared for overrepresentation in linkage regions.
DE, number of transcripts differentially expressed at q < 0.1 by ANOVA that are located in the linkage region
Number of transcripts on the chip that are located in the linkage region
p-values are from Fisher’s Exact test comparing transcripts DE at q < 0.1 to all transcripts on the Affymetrix HGU133Plus2 GeneChip in each linkage region.
