Figure 1

Linkage disequilibrium (LD) plot across the prolactin (PRL) locus for all racial/ethnic groups combined. The horizontal black line depicts the 59-kilobase region of chromosome (chr) 6 analyzed in our multiethnic panel. The PRL gene is shown in grey (RefSeq gene = completed genes from the human genome assembly). Alternative exon 1a (associated with the distal extra-pituitary promoter region) lies 5.8 kb upstream of exon 1 (associated with the pituitary promoter region). The 80 single nucleotide polymorphisms (SNPs) used for genetic characterization are listed below the black line. The LD plot, presented at the bottom of the figures, is based on the measure of D'. Each diamond indicates the pairwise magnitude of LD, with dark grey indicating strong LD (D' > 0.8) and a logarithm of odds score of greater than 2.0.
