Linkage disequilibrium (LD) patterns for significant SNPs on chromosome 1 (a), 2 (b) and 3 (c). Values in boxes are D' values between SNP pairs and the boxes are coloured according to the standard Haploview colour scheme: LOD>2 and D'=1, red; LOD>2 and D'<1, shades of pink/red; LOD<2 and D'=1, blue; LOD<2 and D'<1, white (LOD is the log of the likelihood odds ratio, a measure of confidence in the value of D'). LD blocks are marked with triangles.
