Differences in expression rather than methylation at placenta-specific imprinted loci is associated with intrauterine growth restriction

Abstract excerpt

BACKGROUND: Genome-wide studies have begun to link subtle variations in both allelic DNA methylation and parent-of-origin genetic effects with early development. Numerous reports have highlighted that the placenta plays a critical role in coordinating fetal growth, with many key functions regulated by genomic imprinting. With the recent description of wide-spread polymorphic placenta-specific imprinting, the...
