A comparative study in multiple myeloma (MM) patients with or without anemia, showed an inverse correlation between the expression of TRAIL (and Fas-L) in malignant plasma cells and the relative erythroblast numbers, with a higher percentage of immature erythroblasts in enriched erythroblast populations from anemic MM patients [93]. Here, TNFSF10 is linked to Miyoshi myopathy.
