We have a make update-seqs task that fetches sequences from IMGT and stores them in:
https://github.com/IEDB/MRO/blob/master/ontology/chain-sequence.tsv
Sometimes IMGT changes a sequence that we had previously stored, for example:
https://github.com/IEDB/MRO/pull/41/files#diff-10783046cde2b2261cb684331c670c2cR173
What should we do when we see upstream changes like this? @rvita @acrinklaw
