Abstract excerpt
Genomic imprinting is an epigenetic mechanism resulting in the preferential expression of the maternal or paternal alleles of a specific subset of genes in the mammalian genome. A key but relatively unexplored question is how imprints are established in the germline. New observations on two classical imprinting disorders, the Prader-Willi (PWS) and Angelman (AS) syndromes, offer the first genetic insight into...
