BCL11A and thalassemia: Microarray analysis of CD34+-derived erythroid cells from the hereditary persistence of fetal hemoglobin deletion type-2 (HPFH-2) patients (n = 2), δβ–thalassemia patients (n = 2), and healthy controls (n = 3), demonstrated up-regulation of 12 microRNAs (miRNAs) targeting BCL11A, namely, miR-21, miR-23b, miR-29a, miR-29b, miR-29c, miR-146a, miR-146b-5p, miR-148a, miR-148b, miR-128, miR-181a, and miR-590-5p.
