CCDC69 and cancer: While we know that these nine genes are downregulated with HDAC7 knock-down and three of them are ZNF92 targets (FIBCD1, GDPD5, and GPR56/ADGRG1), they have not been extensively studied in cancer; a PubMed search with the keyword cancer returned less than twenty publications for FIBCD1 (n = 7), CACNG4 (n = 7), CCDC69 (n = 8), MAP6 (n = 11) and GDPD5 (n = 19).
