Figure 5

Old World LP genotype-phenotype correlation, obtained by calculating the quantitative difference between observed LP phenotype frequency and that predicted using frequency data on all 4 LP-associated alleles. Positive and negative values represent cases of LP-correlated genotype under- and over-predicting the LP phenotype, respectively. Dots represent LP phenotype collection locations, crosses represent data collection locations for all currently known 4 LP-correlated alleles, and diamonds represent -13,910 C>T only data collection locations. Colour key shows the values of the predicted LP phenotype frequencies (Figure 2) subtracted from the observed LP phenotype frequencies (Figure 1).
