Fig. 4From: Whole transcriptome analysis of human erythropoietic cells during ontogenesis suggests a role of VEGFA gene as modulator of fetal hemoglobin and pharmacogenomic biomarker of treatment response to hydroxyurea in β-type hemoglobinopathy patientsPairwise linkage disequilibrium (LD) calculations for the tagSNPs of interest across the VEGFA gene (CEU). LD is measured as D′ and R 2 (see also Additional file 1: Table S2)Back to article page
