Figure 2.

Pattern of LD within GABRA2. The numbers on the X- and Y-axes correspond to 21 markers selected to cover the GABRA2 gene relatively evenly at an average spacing of 10.6 kb, plus two flanking markers; the markers are numbered in table 1. Each colored circle represents the LD between two markers, as measured by D′ (Abecasis and Cookson 2000). Higher values of D′ indicate higher LD.
