Figure 1A. Genetic variation at the human TH locus.
LD blocks across the locus in 4 biogeographic ancestry groups. Common (minor allele frequency >10%) SNPs used to demonstrate LD (numbering from the ATG translational start codon): C-824T, G-801C, A-581G, G-494A, G1862A, G2066A, G2426C, G3034A, T3832C, C4581T, G4779A, C5162G, and T6681C. LD blocks were assigned by the solid spline method in Haploview. The TH exon/intron structure is superimposed above each panel; there were no common variants in the final (most 3′) exon.
