NCIT Mouse Strains - The Inbred Mouse terminology in NCI Thesaurus was based on Jax mice strains, hosted in International Mouse Strain Resource (IMSR). This terminology is provided to facilitate MMHCC and caMOD projects.
Uniprot solution seems reasonable. More lightweight than EFO and I think a flat list should be sufficient. It may be that EFO has some of these terms too. In that case we can check if they have a mapping to Uniprot terms and request that they fold one in if not.
