Among these proteins, the BRD4, CAST, and KLF6 genes show co-expression with BAG3 in idiopathic CM based on WGCNA; the genes ARFGAP3, RBM34, BAG3, BCCIP, BID, DNTTIP2, EBNA1BP2, EIF4A3, EIF5, ENAH, FOSL2, HSPA6, PRPF4, PUS7, RND3, SFPQ, SGK1, U2AF2, and ZMYND8 show co-expression with BAG3 in ischemic CM based on WGCNA. The gene discussed is SFPQ; the disease is cutaneous mastocytosis.
