The expression levels of PVT1 and MYC in plasma cells were significantly higher in MM (mean: PVT1 2.58, MYC 0.74) than in MGUS (mean: PVT1 0.88, MYC 0.06) and the control (mean: PVT1 0.06, MYC 0.07) (p < 0.001, p < 0.001, respectively; Figure 1A,B). The gene discussed is MYC; the disease is Miyoshi myopathy.
