This INDEL has been mentioned in several important studies, such as the study with osteosarcoma, in which the analysis negatively correlated the expression of miRNA548 with the expression of KRAS, a gene active in the process of tumorigenesis and metastasis of several types of cancer, including gastric adenocarcinoma [18,19,20]. The gene discussed is KRAS; the disease is gastric adenocarcinoma.
