LAMP5 and Miyoshi myopathy: In this study, we analyzed the GSE6477 dataset to identify differentially expressed genes (DEGs) between newly diagnosed MM (NDMM) and healthy donors (HD) (19, 20), NDMM and relapsed MM (RMM), and found that lysosome associated membrane protein 5 (LAMP5) may have an important role in the occurrence and relapse of MM.
