Background: Maternal obesity can have long-term consequences for the offspring’s health, including increased risk of type-2 diabetes and cardiovascular disease. The C19MC imprinted locus on chromosome 19q13.4 comprises a cluster of 46 microRNAs, which are usually expressed only in the placenta and from the paternal allele exclusively. Besides its role favouring trophoblast migration, the C19MC locus is deregulated in several human cancers. It is unknown ...

Background: The C19MC locus microRNA gene cluster is imprinted in the placenta. Imprinted genes control prenatal development and placental functions, and are epigenetically regulated. The factors that affect the DNA methylation status of C19MC regulatory region are unknown, as is the impact of this differential methylation on the offspring’s body size.Objectives: To study in humans 1) the association of placental C19MC DNA...
