Genotype-Epigenotype Interaction at the IGF2 DMR

Paternally expressed Insulin-like Growth Factor II (IGF2) encodes a gene whose protein product functions as a potent growth mitogen. Overexpression of IGF2 has been implicated in a wide number of disorders and diseases. IGF2 is regulated in part by differential methylation of the two parentally derived alleles. The differentially methylated region (DMR) located upstream of the imprinted promote...

An association between variants in the IGF2 gene and Beckwith-Wiedemann syndrome: interaction between genotype and epigenotype.

Beckwith-Wiedemann syndrome (BWS) is a fetal overgrowth disorder involving the deregulation of a number of genes, including IGF2 and CDKN1C, in the imprinted gene cluster on chromosome 11p15.5. In sporadic BWS cases the majority of patients have epimutations in this region. Loss of imprinting of the IGF2 gene is frequently observed in BWS, as is reduced CDKN1C expression related to loss of mate...

I-50: Embryo Loss Due to Epigenetic Anomaliesin the Male Germ Line: Role of Estrogen

Background: To investigate if aberrant methylation and expression of imprinted genes of the Igf2-H19 locus in the spermatozoa and embryos could be a paternal epigenetic factor involved in early embryo loss To elucidate the role of estrogen in acquisition of the imprinting at the Igf2-H19 locus during spermatogenesis Materials and Methods: Adult male rats of Holtzman strain were administered tam...

The IG-DMR and the MEG3-DMR at Human Chromosome 14q32.2: Hierarchical Interaction and Distinct Functional Properties as Imprinting Control Centers

Human chromosome 14q32.2 harbors the germline-derived primary DLK1-MEG3 intergenic differentially methylated region (IG-DMR) and the postfertilization-derived secondary MEG3-DMR, together with multiple imprinted genes. Although previous studies in cases with microdeletions and epimutations affecting both DMRs and paternal/maternal uniparental disomy 14-like phenotypes argue for a critical regul...

Methylation Status of H19/IGF2 Differentially Methylated Region in in vitro Human Blastocysts Donated by Healthy Couples

Backgrund: Imprinted genes are a unique subset of few genes, which have been differentially methylated region (DMR) in a parental origin-dependent manner during gametogenesis, and these genes are highly protected during pre-implantation epigenetic reprogramming. Several studies heve shown that the particular vulnerability of imprinting genes during suboptimal pre- and peri-conception microenvir...
