The February 2002 mouse (Mus musculus) genome assembly is based on the MGSCv3 Whole Genome Shotgun assembly produced at the Broad Institute using their Arachne software.

### Sample position queries

A genome position can be specified by the accession number of a sequenced genomic clone, an mRNA or EST or STS marker, or a cytological band, a chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list provides examples of various types of position queries for the mouse genome. See the User's Guide for more information.

Request: | Genome Browser Response:
chr16 |  | Displays all of chromosome 16
chr16:1-5000000 |  | Displays first 5 million bases of chr 16
D16Mit120 |  | Displays region around STS marker DMit16120 from the MGI consensus genetic map. Includes 100,000 bases on each side as well.
D16Mit203;D16Mit70 |  | Displays region between STS markers D16Mit203 and D16Mit70. Includes 100,000 bases on each side as well.
AW045217 |  | Displays region of EST with GenBank accession AW045217
Ncam2 |  | Displays region of genome with official MGI mouse genetic nomenclature Ncam2
pseudogene mRNA |  | Lists transcribed pseudogenes but not cDNAs
zinc finger |  | Lists many zinc finger mRNAs
kruppel zinc finger |  | Lists only kruppel-like zinc fingers
huntington |  | Lists candidate genes associated with Huntington's disease
Xu,C.S. |  | Lists mRNAs deposited by co-author C.S. Xu
Use this last format for author queries. Although GenBank requires the search format Xu CS, internally it uses the format Xu,C.S..
