Figure 1

A partial linkage disequilibrium (LD) map of the human CASR (calcium-sensing receptor) gene. Rs numbers for polymorphisms in this gene are shown at the top. The triangle points to the predicted LD block. The rectangles indicate the correlation coefficient (r²) values between the different polymorphisms; the darker the color, the higher the r² values. This figure was obtained using Haploview [22] with the genotype data for Caucasian samples posted at the HapMap database [20, 21].
