CCR1 and multiminicore myopathy: Subsequently, we identified 13 immune-related genes overlapped in the PPI hub genes, WGCNA hub genes, and the immune genes set, as shown in the Venn plot (Figure 7B), including CTSS, NPPA, PTPN11, FGR, SYK, TLR8, IL13, CSF2RB, CCR1, MAP2K1, CXCR1, and TGFB2. To screen biological differences of the immune-related genes between MMD and the control group, GO and KEGG functional analyses for the identified immune genes were performed as well and showed results similar to those of the core genes.
