SNP networks when PLINK threshold=0.1 of T1D study. SNP networks were constructed based on the P-value of PLINK epistasis test using Cytoscape, all the pairwise SNP-SNP interactions that had a PLINK P-value smaller than 0.1 were involved in this SNP network. Each node in the figure is labeled as its SNP ID and the edge between two SNPs indicates whether this pair of SNPs are interacted under a P < 0. 1 significance level. This network includes 2 individual networks and 51 SNPs.
