Online Mendelian Inheritance in Man (OMIM) is a database that catalogues all the known diseases with a genetic component, and — when possible — links them to the relevant genes in the human genome and provides references for further research and tools for genomic analysis of a catalogued gene.[1] OMIM is one of the databases housed in the U.S. National Center for Biotechnology Information (NCBI) and included in its search menus.[2]

Versions[]

Mendelian Inheritance in Man was started in the early 1960s[3] and is available as a book currently in its 12th edition.[4] The online version, OMIM, has been available since 1987,[5] moved to the World Wide Web by NCBI in 1995,[3] and in 2004 contained more than 15,000 records.[1]


Collection process[]

The information in this database is collected and processed under the leadership of Dr. Victor A. McKusick at Johns Hopkins University, assisted by a team of science writers and editors. Relevant articles are identified, discussed and written up in the relevant entries in the MIM database

The MIM code[]

Every disease and gene is assigned a six digit number of which the first number classifies the method of inheritance.

If the initial digit is 1, the trait is deemed autosomal dominant; if 2, autosomal recessive; if 3, X-linked. Wherever a trait defined in this dictionary has a MIM number, the number from the 12th edition of MIM, is given in square brackets with or without an asterisk (asterisks indicate that the mode of inheritance is known; a number symbol (#) before an entry number means that the phenotype can be caused by mutation in any of two or more genes) as appropriate e.g., Pelizaeus-Merzbacher disease [MIM #312080] is an X-linked recessive disorder.

First Digit Range of MIM codes Method of inheritance
1 100000-199999 Autosomal loci or phenotypes (created before May 15, 1994)
2 200000-299999 Autosomal loci or phenotypes (created before May 15, 1994)
3 300000-399999 X-linked loci or phenotypes
4 400000-499999 Y-linked loci or phenotypes
5 500000-599999 Mitochondrial loci or phenotypes
6 600000- Autosomal loci or phenotypes (created after May 15, 1994)

These codes have been used in the medical literature to provide a unified index to genetic diseases.[6]
