Interestingly, the levels of ZNF802 expression in erythroblasts in the β0-thalassemia/HbE group (n = 9) cultured at day 8 and day 10 were significantly lower than in erythroblasts from healthy donors (n = 5; p-value = 0.04) (Fig. 1C) and had a strong negative correlation (r = -0.85; p-value = 0.0004) with the levels of HbF at day 14 (Fig. 1D). This evidence concerns the gene JAZF1 and thalassemia.
