MGI has integrated the latest C57BL/6J assembly, GRCm39. This includes annotations from NCBI and Ensembl, and updated coordinates for genome features, transcription start sites, and gene traps. SNP coordinates in MGI were not updated to GRCm39 for this release, but will be in a future release.
MGI now loads vertebrate orthology data based on the “stringent” set of homology class data from the Alliance of Genome Resources. These data include human, rat, and zebrafish homologs.
