Figure 1.

Positional location of the superoxide dismutase (SOD) 3 polymorphisms. From top to bottom, this schematic shows 7,500 base pairs (7.5 kb) of the human SOD3 gene (chromosome 4): amplicons used for resequencing are shown by boxes, with chevrons with the amplicon name to the left; single-nucleotide polymorphisms that have been identified in this study and dbSNP identifiers are indicated by vertical bars; the last line shows the location of exons 1–3 (boxes), with triangles indicating introns; sequences are read from left to right (5′→3′). SNP = single-nucleotide polymorphism.
