The rationale of choosing these CNA associated genes was basically due to LRP12, TPM2, EGFR, CCND1 being matched with ICGC and TCGA databases whereas FSCN1, CLPTM1L, CHL1 and CSMD1 had been found to be associated with oral cancer [12, 31–33]. This evidence concerns the gene CCND1 and lip and oral cavity carcinoma.
