Abstract excerpt
Genomic imprinting is the process in mammals by which gamete-specific epigenetic modifications establish the differential expression of the two alleles of a gene. The tightly linked H19 and Igf2 genes are expressed in tissues of endodermal and mesodermal origin, with H19 expressed from the maternal chromosome and Igf2 expressed from the paternal chromosome. A model has been proposed to explain the reciprocal...
