Gene function and KEGG results indicated that the main molecular mechanism of the SGJY capsule in the treatment of MMD was the PI3K-Akt signaling pathway, KDR, CDK6, IGF1R, EGFR, INSR, GSK3B, HSP90AA1, PIK3CG, MCL1, PIK3R1, and AKT1 genes were enriched in it. The gene discussed is IGF1R; the disease is multiminicore myopathy.
