Considering the CC GO terms, terms associated with mitochondrial respiratory chain complex I (GO:0005747) III (GO:0005750) and IV (GO:0005751) were enriched in BD vs KIS, BP vs KIS, DD vs KIS and DP vs KIS with mitochondrial proton-transporting ATP synthase complex and coupling factor F(o) (GO:0000276) enriched in only the BP vs KIS and DP vs KIS (Additional file 13). Here, CXCR1 is linked to Behcet disease.
