MirGeneDB is a database of manually curated microRNA genes that have been validated and annotated as initially described in Fromm et al. 2015[1] and Fromm et al.

2020.

[2] MirGeneDB 2.1[3] includes more than 16,000 microRNA gene entries representing more than 1,500 miRNA families from 75 metazoan species and published in the 2022 NAR database issue.

All microRNAs can be browsed, searched and downloaded.
