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.

约80%的印记基因呈串出现在染色体上；在哺乳动物品种之间，印记基因具有较高的保守性；印记基因的复制通常表现为不同时性；一些印记基因具有印记遗传的时空性；少数印记基因只转录为mRNA而不翻译成蛋白质；印记基因的反意链通常表达，表达产生具有调节印记基因的作用。
