Fig. 3 The PCR results of the affected person, A. N. Ethidium
bromide-stained 3% agarose gels illustrating the PCR products. Lane
1: undigested PCR product; lane 2: PCR-RFLP by NciI.; and lane 3:
genetic markers. The normal control showed a single band of 433 bp,
while A. N., having three bands of 192, 157, and 84 bp, was
characterized as if in a homozygous state because the α2 globin gene
on the other side of the chromosome was entirely deleted because of
SEA deletion
