Fig. 3From: The genetics of smoking in individuals with chronic obstructive pulmonary diseaseRegion plots of the smoking associated loci. The Y axis represent the P values in the (−log10 scale) and the X axis is the genomic position. Gene names and their corresponding coordinates are shown below. The sentinel SNP is shown as a purple diamond and the color coding of SNPs reflects the degree of linkage disequilibrium (LD) with the sentinel SNP using 1000G referenceBack to article page
