Table 1:
Enrichment results of Alzheimer’s disease (AD) genes using MSigDB gene-sets. The initial AD gene list consists of 61 genes, and those gene-sets with Fisher’s test p-value smaller than 0.05/Ngs, where Ngs is the number of gene-sets within each major collections (h,c2,··· c7), are marked with “Y” under n1 = 61 column. Those with q-value smaller than 0.05 are marked by Yq. “pv(corr)” is Bonferonni-corrected p-value which is Fisher’s p-value multiplied by Ngs.“qv” is the q-value. “overlap” is defined as which measure the proportion of overlapping genes in the geometric mean of the two gene lists. Three other AD gene lists are used for the same enrichment analysis: n1 = 58 removes the three autosomal dominant AD (ADAD) genes (APP, PSEN1, PSEN2); n1 = 48 removes all genes where the associated variant allele is rare (minor allele frequency < 0.01); n1 = 47 removes all genes where the odds-ratio (OR) of the associated variant is known to be within (0.9, 1.1). A gene-set is marked as “Y*” if p-value is smaller than 0.05/Nallgs where Nallgs = 17484 is the total number of gene-sets in MSigDB. Due to space limitation, gene-sets in gone-ontology collection (c5) are not listed if 0.01 < q-value < 0.05 and p-vale > 0.05/Ngs: 75 for n1 = 61 AD gene list; 3 for n1 = 58 list; 17 for n1 = 48 list; and 39 for n1 = 47 list.
