  Increased Hemoglobin A2 (HbA2) levels are used as invaluable markers for the detection of beta-thalassemia (β-thalassemia) carriers. However, a concomitant delta-globin gene (HBD) mutation reduces the HbA2 level resulting in the confusion of the β-thalassemia status. Objectives: We sought to identify HBD mutations leading to low HbA2 level β-thalassemia carriers receiving the molecular diagnosis at the Institute for Medical Research (IMR), Malaysia. Methods: Thirty-seven β-thalassemia carriers were ruled out of alpha-thalassemia (α-thalassemia) and underwent HBD genotyping by Sanger sequencing. Results: Twenty-two β-thalassemia carriers with HBD mutations were identified. The most common mutations were HbA2-Indonesia and HbA2-Deventer. The HbA2-Deventer was found in et.. View more»
