Rat Models of Human Diseases and Related Phenotypes: A Novel Inventory of Causative Genes

The laboratory rat (Rattus norvegicus) has been used for a long time as the model of choice in several biomedical disciplines. In 2020, I made an inventory of rat genes that had been identified as underlying diseases or playing a key role in critical biological processes that are altered in diseases. Over 350 genes could be found, a significant number of which have similar effects in rat and humans (Szpirer in J Biomed Sci 27:84–155, 2020). However, a few rat disease genes were unintentionally overlooked; in addition, since this review was published, numerous rat genes were inactivated by targeted mutations, revealing their potential role in diseases. It thus seems appropriate to update these data, which is the aim of this paper.
