Description

This track shows the cytogenetic locations of phenotype entries in the Online Mendelian Inheritance in Man (OMIM) database for which the gene is unknown.

Display Conventions and Configuration

Cytogenetic locations of OMIM entries are displayed as solid blocks. The entries are colored according to the OMIM phenotype map key of associated disorders:

Lighter Green for phenotype map key 1 OMIM records - the disorder has been placed on the map based on its association with a gene, but the underlying defect is not known.
Light Green for phenotype map key 2 OMIM records - the disorder has been placed on the map by linkage; no mutation has been found.
Dark Green for phenotype map key 3 OMIM records - the molecular basis for the disorder is known; a mutation has been found in the gene.
Purple for phenotype map key 4 OMIM records - a contiguous gene deletion or duplication syndrome; multiple genes are deleted or duplicated causing the phenotype.

Gene symbols and disease information, when available, are displayed on the details pages.

The descriptions of OMIM entries are shown on the main browser display when Full display mode is chosen. In Pack mode, the descriptions are shown when mousing over each entry. Items displayed can be filtered according to phenotype map key on the track controls page.

Methods

This track was constructed as follows:

The data file genemap.txt from OMIM was loaded into the MySQL table omimGeneMap.
Entries in genemap.txt having disorder info were parsed and loaded into the omimPhenotype table. The phenotype map keys (the numbers (1)(2)(3)(4) from the disorder columns) were placed into a separate field.
The cytogenetic location data (from the location column in omimGeneMap) were parsed and converted into genomic start and end positions based on the cytoBand table. These genomic positions, together with the corresponding OMIM IDs, were loaded into the omimLocation table.
All entries with no associated phenotype map key and all OMIM gene entries as reported in the "OMIM Genes" track were then excluded from the omimLocation table.

Data Access

+Since OMIM has only allowed Data queries within individual chromosomes, no download files are +available from the Genome Browser. Full genome datasets can be downloaded directly from the +OMIM Downloads page. +All genome-wide downloads are freely available from OMIM after registration.

+If you need the OMIM data in exactly the format of the UCSC Genome Browser, +for example if you are running a UCSC Genome Browser local installation (a partial "mirror"), +please create a user account on omim.org and contact OMIM via +https://omim.org/contact. Send them your OMIM +account name and request access to the UCSC Genome Browser 'entitlement'. They will +then grant you access to a MySQL/MariaDB data dump that contains all UCSC +Genome Browser OMIM tables.

+UCSC offers queries within chromosomes from +Table Browser that include a variety +of filtering options and cross-referencing other datasets using our +Data Integrator tool. +UCSC also has an API +that can be used to retrieve data in JSON format from a particular chromosome range.

+Please refer to our searchable +mailing list archives +for more questions and example queries, or our +Data Access FAQ +for more information.
