The heatmap showed that the expression of nine m6A methylation regulators (FTO, HNRNPC, IGF2BP3, KIAA1429, METTL16, METTL14, METTL3, RBMX, and ZC3H13) were differentially expressed in MM patients compared to normal volunteers (Figure 1A). The gene discussed is VIRMA; the disease is Miyoshi myopathy.
