						 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»
