Construction of PPI network and analysis of modules. a Construction of PPI network using MG risk genes and identification of modules. All of circles represent MG risk genes, whereas green circles represent genes in the modules. Lines represent interactions between proteins encoded by MG risk gene. b GO functional analysis of modules. The degree of enrichment increases from green to red. Larger circles indicate a more significant proportion of MG risk genes in a module among GO function genes. c Pathway enrichment analysis of modules. The degree of enrichment increases significantly from green to red. Larger circles indicate a larger proportion of MG risk genes in a module among KEGG pathway genes
