  2. Top genes with a CFG score of 4 and above (n=42) are shown. A more complete list of genes with CFG score of 3 and above (n=186) is available in the Supplementary Information. Gene symbols underlined are blood biomarker candidate genes. Best P-value SNP within the gene or flanking regions are depicted. P-values in bold are <0.001. The last two columns depict gene-level replication of findings, that is, best P-value SNPs in the same gene from two other independent cohorts (GAIN EA and GAIN AA). In total, 37 of our top 42 genes (88.1%) had at least a SNP with P<0.05, in both the GAIN-EA cohort and in the GAIN-AA cohort.
