The transcription factor GATA-1, together with its cofactor FOG-1, regulates erythropoiesis and megakaryocytopoiesis. Mutations in the DNA or FOG-1 binding sites of its N-terminal zinc finger result in different illnesses. Alterations of the FOG-1 face are responsible for dyserythropoietic anemia with thrombocytopenia while R216Q, the only mutation identified in the DNA face, induces X-linked thrombocytopenia with thalassemia (XLTT). The former disorder has been studied in detail whereas little… CONTINUE READING
