Our criteria for pairing genomic biomarkers with targeted drugs is based upon the verified gene-drug lists available from the NCI (https://www.cancer.gov/about-cancer/treatment/drugs/childhood-cancer-fda-approved-drugs), the Memorial Sloan Kettering Cancer Center Precision Oncology Knowledge Base (OncoKB) (21) and the Jackson Laboratory Clinical Knowledgebase (JAX CKB) (22). This evidence concerns the gene CKB and cancer.
