Ensembl Mouse is based on the April 2007 Mus musculus (strain C57BL/6J) high coverage assembly (NCBI m37). This assembly is used by UCSC to create their mm9 database.
The Mouse Genome Sequencing Consortium is a joint project between
The Whitehead Institute/MIT Center for Genome Research,
The Washington University Genome Sequencing Center,
The Wellcome Trust Sanger Institute
and EMBL - EBI to provide the Mouse genome sequence to the world.
We work closely with other Mouse groups to provide an integrated resource (see below for credits).
There are some major changes in the assembly from version m36; for more details see the NCBI build statistics .
