In the primary RCC tumor cases, the most commonly affected genes were, by frequency, VHL (von Hippel-Lindau tumor suppressor), PBRM1 (polybromo 1), TTN (titin), MUC16 (mucin 16, cell surface associated), SETD2 (SET domain containing 2, histone lysine methyltransferase), BAP1 (BRCA1 associated protein 1), LRP2 (LDL receptor related protein 2), DST (dystonin), KMT2C (lysine methyltransferase 2C), and TP53 (tumor protein p53) [28]. The gene discussed is TTN; the disease is renal cell carcinoma.
