We observed that some of the top differentially expressed genes are known MM biomarkers: CTAG2, MAGEA6, MAGEA1, and SSX1, whereas some genes within the M20 module were differentially expressed, but not well known in the context of MM biology (SOHLH1, GABRA3, GABRB2, HTR2C, and GLDC). Here, CTAG2 is linked to Miyoshi myopathy.
