Li et al. [13] detected the relative expression of AIM2 in the MM group and the control group by quantitative real-time PCR and found there were no differences in the expression of AIM2 (p = 0.079), but the control samples they chose were from patients with iron deficiency anemia, and they didn’t describe whether they isolated normal plasma cells. The gene discussed is AIM2; the disease is Miyoshi myopathy.
