Rapid Screening for Deleted Form of β-thalassemia by Real-Time Quantitative PCR.


ABSTRACT: Thalassemia is the most common single gene disease in human beings. The prevalence rate of β-thalassemia in Taiwan is approximately 1-3%. Previously methods to reveal and diagnose severe deleted form of α- or β-thalassemia were insufficient and inappropriate for prenatal diagnosis. A real-time quantitative PCR method was set up for rapid screening of the deleted form of β-thalassemia. Our results show that ΔΔCt between deleted form of β-thalassemia and normal individuals were 1.0674 ± 0.0713. On the contrary, mutation form β-thalassemia showed no difference with normal healthy control. The HBB/CCR5 ratio for deleted form of β-thalassemia patients was 0.48, whether normal individuals and mutation form of β-thalassemia was 1.0. This RQ-PCR technique is an alternative rapid screening assay for deleted form of β-thalassemia. In addition, it could also identify undefined type. Our technique by using RQ-PCR to quantify gene copies is a reliable and time-saving method that can screen deleted form of β-thalassemia.
