The common features of imprinted genes are, clustering of multiple imprinted genes in one chromosomal region (around 80%), conservation of imprinting among eutherian mammals, asynchrony of DNA replication of imprinted genes, temporal and spatial regulation of expression of imprinted genes, coding for untranslated RNAs as well as proteins, antisense transcripts may regulate expression of imprinted genes. Once established, the imprinting pattern is stably transmitted through cell division but reset in germ cells of the fetal gonads.
