IS: intronic sequence, Nb: number. The intron phase was defined as follows: phase 0 introns are inserted between two codons; phase 1 introns are inserted after the first nucleotide of the codon, and phase 2 introns are inserted between the second and the third nucleotide of the codon.
(*) The gene is truncated and the 5′ exon is missing.
