Moreover, when considering cumulative incidence of mortality without previously documented MM progression in patients not receiving an auto-SCT, the differences between genetic groups were even more evident: 21.2% of patients with CD200 rs1131199 GG genotype vs 10.5% for patients with pooled CC or CG genotypes (p: 0.02) (Figure 4B). Here, CD200 is linked to Miyoshi myopathy.
