We assessed a detailed investigation of the methylation status of the 11p15 ICR1 CBS1-7, IGF2DMR0 and H19DMR (H19 promoter) in a population of controls (n=50) and RSS carrying (n=104) or not (n=65) carrying a hypomethylation at the 11p15 ICR1 region.

On the other hand, the recent identification of unexpected genetic defects in BWS and SRS patients also brought new insights into the mechanisms of 11p15 imprinting regulation.

DNA methylation defects involving ICR1 result in two growth disorders with opposite phenotypes: an overgrowth disorder, the Beckwith-Wiedemann syndrome (maternal ICR1 hypermethylation in 10% of BWS cases) and a growth retardation disorder, the Silver-Russell syndrome (paternal ICR1 loss of methylation in 60% of SRS cases).

In 35-60% of SRS cases the paternally methylated imprinting control region (ICR) upstream of the H19 gene (H19-ICR) is hypomethylated, leading to downregulation of IGF2 and bi-allelic expression of H19.

The H19 gene is abundantly expressed by the human placenta and is implicated in the pathogenesis of congenital growth disorders such as Beckwith-Wiedemann (BWS) and Silver-Russell (SRS) syndromes.

Hypomethylation of the differentially methylated region (DMR) of the H19 gene and uniparental disomy of maternal chromosome 7 is present in ∼45% of the patients with SRS so more than half of these patients have no known genetic etiology.

DNA methylation defects involving the ICR1 H19/IGF2 domain result in two growth disorders with opposite phenotypes: an overgrowth disorder, the Beckwith-Wiedemann syndrome (maternal ICR1 gain of methylation in 10% of BWS cases) and a growth retardation disorder, the Silver-Russell syndrome (paternal ICR1 loss of methylation in 60% of SRS cases).
