The screening for mutations on a Sequenom MassARRAY platform did not show any mutations in the 10 examined genes (ALK, BRAF, DDR2, EGFR, ERBB2, KRAS, MAP2K1, NRAS, PIK3CA, RET) in the DALM or in the first adenocarcinoma removed a few years before the kidney transplant. This evidence concerns the gene ERBB2 and adenocarcinoma.
