OMIM Data Downloads


In addition to searching OMIM through the website, OMIM offers a number of data files that are updated nightly and are available for download following a registration and review process. Registration is necessary to keep a record of downloads for funding purposes* and to notify users of changes and updates. One file, mim2gene.txt, is provided without registration to help interconnectivity of MIM numbers among other data resources.

File Name File Description
mim2gene.txt A tab-delimited file linking MIM numbers with NCBI Gene IDs, Ensembl Gene IDs, and HGNC Approved Gene Symbols.
