Fig. 2From: Stratified analyses of genome wide association study data reveal haplotypes for a candidate gene on chromosome 2 (KIAA1211L) is associated with opioid use in patients of Arabian descentRegional Manhattan plot of the chromosome 2q11.2 region showing the FaSTLMM analysis of the opioid use disorder patients compared to controls. The LD heat map is based on the hg19/1000genomes NOV/2014 reference set. The SNPs are colour coded according to r2 measured based on the pairwise LD with the index SNP rs10175560 (p-value = 2.24 × 10 − 7) shown in purple. Two other SNPs mapped to the KIAA1211L gene clustered in high LD indicating a possible candidate locus for opioid use disorderBack to article page
