Table 2 shows data on KRAS, NRAS, and BRAF gene mutations, or their combination, detected in bone marrow and the ctDNA of patients with and without plasmacytomas. It should be noted that NRAS and BRAF mutations in the bone marrow of patients with plasmacytomas are detected somewhat more often than in patients without plasmacytomas, but the differences are not significant. Here, NRAS is linked to plasmacytoma.
