An addition/deletion/substitution type claim can be defined with elements 1) - 3) listed below.

• 1) One or more nucleotide sequences or amino acid sequences defined in, for example, working example
  
• 2) A clear definition of the term "addition, deletion, substitution," provided that "the sequences added, deleted or substituted" have a high degree of identity (homology) with the sequences of 1)
  (The definition may be provided in the detailed description of the invention.)
  
• 3) Property or function of encoded protein
  (Such a claim limitation needs to be the one which distinguishes the encoded protein from other proteins. The property or function may be specifically defined not in the claim but in the detailed description of the invention.)

In addition, although it is not necessary to specify the exact number of bases which may be added, deleted or substituted, it is expected that the number of bases often represents an important element when a definition of the above-mentioned element 2) is provided.
