A type of embryonic kidney cancer called Wilm’s tumor is associated with the loss of imprinting for two specific genes. This conference aims at bringing together basic research scientists, health care professionals and others from different disciplines in order to share expertise in genomic imprinting and imprinting disorders and provide opportunities for cross-disciplinary collaborations. Genomic imprinting has inspired considerable work in evolutionary theory, in part, because the use of just one copy of a gene when an organism has two requires some sort of evolutionary explanation. Similarly, the phylogenetic distribution of imprinting, as well as the chromosomal clustering of many (but not all) imprinted genes, both demand and suggest evolutionary hypotheses. Genomic imprints may be covalent (DNA methylation) or non-covalent (DNA-protein and DNA-RNA interactions, genomic localization in nuclear space), and the process of imprinting encompasses the specialized nuclear enzymatic machinery which maintains parental epigenetic markings throughout the cell cycle.

Nuclear transplantation was used to make embryos that had only one of the two sets of Our lab further enhanced these carcinogenic studies by showing that the phenomenon of genomic imprinting evolved approximately 150 million years ago with the advent of placentation and viviparity in a common ancestor to Therian mammals (Killian et al, 2000, Killian et al, 2001A, Killian et al, 2001B, Nolan et al, 2001).

Genomic imprinting is an epigenetic process, which via DNA and histone methylation restricts the expression of affected genes in a parent-of-origin specific manner. From the perspective of genome encoded function, the corresponding genes represent a haploid genotype.

Genomic imprinting is thought to be a particular sub-type of dominance modification (Sapienza, 1990), whereby imprinting would result when one or more of these modifiers is sex-linked and would therefore produce a dosage difference. Imprinting-like phenomena have been observed in a wide range of phyla from both the plant and animal kingdoms.

X chromosome inactivation and genomic imprinting are classic epigenetic processes that cause disease when not appropriately regulated in mammals. Whereas X chromosome inactivation evolved to solve the problem of gene dosage, the purpose of genomic imprinting remains controversial.
