Functional categories affected in both fibroblasts and monocytes of CHM patients included a large group of genes involved in regulation of cell adhesion and motility (NCAM-2, FMN1, ANKRD28, CSF3R, DMD, MLLT4, DPP4, TSPAN5, CD114, DMD, CYFIP2, WNT5A, MMP7), immune response (IL1, CC2, CFI, ELOVL2), regulation of trafficking and exocytosis (RGS11, SYT 6, GBF1) and transcriptional regulation (HOXD11, MRO, NRG1, NLRC3, NR2F6, SALL1, DIP2A, RSOPO2) (Fig. 7A). This evidence concerns the gene CYFIP2 and choroideremia.
