Which of the following statements about Alpha-Thalassemia is false? It is a condition where hemoglobin contains only beta subunits. This disease is caused by a large DNA deletion between the HBA2 gene and the LUC7L gene. The LUC7L gene is transcribed in the same direction as the HBA2 gene. RNAi mechanisms result in the HBA2 gene getting silenced by DNA methylation.
