Figure 2

Sequencing results for the polymerase chain reaction (PCR) products from different -448G>A genotypes. The single nucleotide polymorphism sites are underlined. The results were completely matched to the corresponding results derived from PCR-restriction fragment length polymorphism genotyping. A: AA variants (reverse strand), B: GG wild type (reverse strand).
