Linkage disequilibrium of the GJA5 3
UTR insertion/ deletion. Linkage disequilibrium relationships (r2) between the Cx40-B promoter SNP (rs10465885), a Cx40-A promoter SNP (rs11552588), the 3′ UTR SNP (rs1043806) used for the allelic expression imbalance assay, the insertion deletion polymorphism (Ins/Del), and four other GJA5 SNPs from the Illumina Hap550 BeadChip. The positions of the SNPs relative to the alternative transcripts for Cx40-A and Cx40-B are displayed. The D′ between rs1043806 and the insertion/deletion is 1.0 (not shown).
