This comparison showed an overlap of five genes (ETV4 (tumor non-malignant signature), STK32A, SPINK1, GOLT1A, KRT6A (adenocarcinomas—squamous cell carcinomas signature)) in the first case, and an overlap in one (KRT15) of the three most prominent genes in the second case. The gene discussed is KRT6A; the disease is squamous cell carcinoma.
