  1. † The top blast hit was cathepsin Y, which is a synonym for cathepsin Z used here.
  2. †† The top blast hit was named VHSV induced protein, but this appears to be a coatomer protein subunit based on similarity to other sequences.
  3. * The blastn similarity score is shown instead of blastx due to the sequence corresponding primarily or completely to the 3' UTR.
  4. Complementary DNA sequences for additional candidate genes were obtained from a follicle/interstitial cell enriched library [29].
