The analysis revealed that our models identified probes associated with genes involved in pathways closely related to multiple myeloma, such as PI3K-Akt (see Supplementary Figure S17), MAPK (see Supplementary Figures S15–S17), Wnt signaling (see Supplementary Figure S16), BRAF and RAF1 fusion signaling (see Supplementary Figure S17), and mTOR pathways (see Supplementary Figure S16). Here, RAF1 is linked to AL amyloidosis.
