In fact, 17 of the 75 investigated MYH9-RD patients (22.6%), 26 of 77 ITP patients (33.8%) and 4 of 32 subjects with other inherited thrombocytopenias (12.5%) had undergone platelet or red blood cell transfusions (a prevalence of transfused patients not significantly different between the three groups). This evidence concerns the gene MYH9 and Thrombocytopenia.
