From: The IGF1 P2 promoter is an epigenetic QTL for circulating IGF1 and human growth
The two IGF1 gene promoters (P1 and P2) are figured in the lower part of the figure (broken arrows show the TSS of each promoter). The upper part of the figure shows the methylation level of each studied CG in the 216 children (mean ± SD). The horizontal black bar encompasses the cluster of six CGs of P2 promoter whose methylation is inversely correlated with height and serum IGF1.
