Features of the cat genome annotation and of other mammalian genomes

aPseudogenes, RNA genes, and genes restricted to the Y chromosome were excluded from this analysis.
bThe percent of NCBI annotated genes represented in cat was calculated excluding any genes that had been withdrawn from NCBI’s Genes database as of September 18, 2006.
cCDS coding sequence is lower than genes in these counts because CDS are exons while genes include exons, introns, and 5′- and 3′-UTRs.
dGenes were considered to have syntenic orthology when the three same genes occur in the same order in the cat genome as in the indexed genome, or when at least one of the genes two neighbors away is also flanking the index species gene (see text). Species with large numbers of unmapped contigs (cow and chimp) show lower syntenic orthology as a consequence, and these estimates should not be considered robust.
