Summary of what we know about genomic imprinting in the brain

What is it about?

Genes in mammals are not always equally expressed from the the two available copies; instead some genes are more expressed either from the maternally- or paternally-inherited copy. These phenomenon is called genomic imprinting and it can vary according to tissue and seems to be particularly abundant in the brain. Here we review the list of genes under genomic imprinting in the brain, their known functions and the molecular mechanisms that control their imprinting status.
