From: UGT1A1 sequence variants and bilirubin levels in early postnatal life: a quantitative approach
Pair-wise linkage disequilibrium (LD) across UGT1A1 using common markers (minor allele frequency ≥ 10%). Black boxes indicate pair-wise D' values ≥ 0.9; dark gray boxes indicate D' values > 0.7 but < 0.9; light gray boxes indicate D' values between 0.5 and 0.7; D' values < 0.5 are indicated by a cross. Two 'blocks' of strong LD (D' ≥ 0.9) are seen at the 5' and 3' ends.
