IL10 and Miyoshi myopathy: Our previous studies in MM patients showed a favourable effect of the CXCL12-3′A variant (rs1801157) with respect to the progression of the disease (less advanced stage) and survival (Mazur et al. 2013) and confirmed the lack of correlations between IL-6 (rs1800795, −174 G > C) and IL-10 (rs1800896, −1082 G > A) SNPs and susceptibility to MM (Mazur et al. 2005).
