GWAS Plot of Gene-Gene Associations illustrates p-values (shown on y-axis) of SNP for gene variants found on chromosomes 1-22(x-axis). The x-axis shows Chromosomes 1 thru 22. Each dot represents gene variants or SNPs. In the circled dots to the extreme left positioned above Chromosome 1 (x-axis), the dot with the highest p-value represents an ABCD3 gene variant with a defined rs# that is strongly interacting with RANGAP1 to influence CaP tumors in African American. All of the dots in the circle reveal an association of SNPs surrounding ABCD3 gene with basal gene expression of RanGAP1. This variation in gene expression RanGAP1 might be influenced by the SNPs in ABCD3 Similarly in the circled points to the far right, positioned above chromosome 12 ( x-axis), the dot with the highest p-value represents the TMTC2 gene variant with a defined rs#, that strongly interacts with STXBP2. All the dots in the circle represent an association of SNPs surrounding TMTC2 gene with basal gene expression of STXBP2.
