LASSO regression was then performed to identify 34 candidate genes closely related to the prognosis of MM patients, including the following 19 genes: HNRNPC, RPLP2, SNRPB, SNRPE, SF3B3, KPNB1, GAPDH, RPS12, NFX1, MTIF3, CIRBP, EXOSC8, RARS2, MRPS31, ZC3H6, DROSHA, NAT10, LSM5, and PRIM1 (Supplementary Figure 1). Here, MRPS31 is linked to Miyoshi myopathy.
