How should sequence variants be presented in a patent application?

According to MPEP 2422.01, sequence variants in patent applications can be presented as follows: Present a single, primary sequence in the specification and “Sequence Listing” by enumeration of its residues. Discuss and/or claim variants of that primary sequence without presenting each variant as a separate sequence in the “Sequence Listing”. Annotate the primary sequence in…
