Conservation categories are defined: Categories A-E: a nucleotide exists in >
95% of the sequences studied. "Category A": the existing nucleotide is 98%-100% conserved.
"Category B": the existing nucleotide is 90%-98% conserved. "Category C": the
existing nucleotide is 80%-90% conserved. "Category D": the existing nucleotide is <
80% conserved. "Category E": sum of Categories A-D. "Category N": nucleotide
exists in < 95% of the sequences studied. Other abbreviations used: IP: intron
position. nt: nucleotide.
