Figure 1.

Detection of PCR products from the multiplexed PCR‐based method by agarose gel electrophoresis. Only deletion alleles were amplified from genomic DNA samples of two DPB patients (DPB002 and DPB023) and of a patient with recurrent airway infections (dd071). Both wild type and deletion alleles were amplified from those of two other DPB patients (DPB058 and DPB132) and two healthy individuals (HS032 and HS107). One reference sample showing homozygous insertion (wild type) and PCR products with no genomic DNA (No template) were also shown as positive and negative controls, respectively
