Our models identified probes whose respective genes are involved in pathways highly related to multiple myeloma, such as the PI3K-Akt, MAPK, JAK-STAT, and Wnt signaling pathways, the RAF/MAP kinase cascade, NF-kB-related pathways, and signaling by RAS and BRAF mutants. The gene discussed is SOAT1; the disease is AL amyloidosis.
