Classes follow those laid down in ref. 4 and are based on the longest transcript of each gene; the total number of exons from all alternative transcripts is 14,640. Known genes, identical to known human cDNA or protein and have an entry in Locuslink; novel genes, have an ORF and are identical to spliced human ESTs or have some similarity to other cDNA/proteins (all species); novel transcripts, similar to novel genes but have ambiguous ORFs or multiple evidence for non-coding RNA; putative genes, with identity to 1–3 spliced ESTs but do not contain evidence for an ORF; pseudogenes, similar to known proteins but contain a frameshift and/or stop codon that disrupts the ORF.
