Liquid biopsy test reported actionable alterations in ARID1A gene, rearranged during transfection (RET) gene fusions, epidermal growth factor receptor (EGFR) gene R776H mutation, breast cancer (BRCA) genes 1/2, and cyclin-dependent kinase inhibitor 2A (CDKN2A) gene mutations. This evidence concerns the gene CDKN2A and cancer.
