The genome feature annotations for the C57BL/6J genome displayed in MGV are taken from MGI’s Unified Mouse Genome Feature Catalog that integrates the genome feature annotations from Gencode, NCBI and miRBase into a single, non-redundant set (11). Currently, only the C57BL/6J assembly and annotations are ‘reference quality’, thus there are some gaps in the annotations which limit the ability of a user to identify equivalent genome features across all of the available genomes. As additional sequence data are generated, improvements will be made to the quality of all the assemblies and their corresponding genome feature predictions.
