CD79A and Miyoshi myopathy: After evaluating the medians, interquartile intervals and the range of the parameters considered (hematocrit, haemoglobin, mean corpuscular volume and RDW) in the whole cohort of MM patients (Supplementary Table 1), we compared each parameter in the three different MM isotypes (Table 2), finding that only the RDW seems to have a discriminating role; in fact, its value is significantly higher in the IgA MM respect to IgG e light chain MM (LCMM).
