info DOI 
info Description of data contents 

LD bin list of D3 (Phase III). LD bin is a group of SNPs that mutually shows high LD (r2 > 0.8). See below for detail.

info Data analysis method 

Common SNPs (MAF > 5%) were selected, and LDs (r2 values) between every SNP pairs within 300 kb were calculated. LD bins were collected so that every pairs within the bin shows r2 >0.8, by the greedy method of tagzilla (which is a rapid method of bin selection based on the principle of ldSELECT (Carson et al., AJHG 74, 106-120, 2004)).
