A prostate cancer related module was investigated (due to its significant enrichment on KEGG prostate cancer pathway), which has DEGs as PDGFRB, PDGFB, SNX2, EGFR and DECGs as (PDGFRA, PDGFRB), (SNX4, PDGFRB), (PDGFB, PDGFRA), (SNX2, PDGFRA), (PDGFRB, PIK3R2), (EGFR, PIK3R2), (EGFR, AREG). The gene discussed is SNX4; the disease is Familial prostate cancer.
