Schematic drawing of the IGF2 and H19 gene loci. IGF2 exons (E), promoters (P1 to P4 and P), differentially methylated regions (DMR1 and 2), the H19 differentially methylated domain (DMD), the quantitative trait nucleotide (QTN) and the microsatellite SWC9 are indicated. CTCF binding sites in P1, P2 and P3 repeats are indicated in the DMD.
