Information about the continuing improvement of the mouse genome
The GRC is working hard to provide the best possible reference assembly for mouse. In the mouse reference assembly, sequences in the primary assembly unit (chromosomes and unlocalized and unplaced scaffolds) come from the C57BL/6J strain. For several genomic regions that are variable between different strains, we provide alternate loci scaffolds comprised of clone-based sequences from a variety of other strains. Additionally, we are releasing regional fixes known as patches. This allows users who are interested in a specific locus to get an improved representation without affecting users who need chromosome coordinate stability.
