In particular, twelve genes (CCND1, CCNL1, CKAP4, CRABP1, FGF3, GRHL2, MYEOV, PKP4, RAP2B, RPL14, SMAD3, ZNF639) were associated with "Carcinoma, Squamous Cell" and eleven genes (CCND1, CKAP4, CRABP1, EVI1, FGF3, MYEOV, PKP4, RPL14, SMAD3,TMEM16A,ZNf639) were associated with "Esophageal Neoplasms". This evidence concerns the gene CKAP4 and neoplasm of esophagus.
