Putative errors were estimated by analyzing the corresponding gene sequences. ^aThe total number of protein sequence errors included in the analysis. ^bThe number of errors resulting from genome sequencing or assembly errors. ^cThe number of missing segments detected in the corresponding gene sequences. ^dThe number of errors resulting from alternative splicing variants reported for homologous genes. ^eThe number of inserted sequence segments detected in the gene sequences of homologous proteins. The number of these inserted sequence segments with at least one stop codon is given in brackets. ^fThe number of errors supported by transcript evidence, i.e. false positive (FP) error predictions. ^gThe percentage of the total number of putative errors that were invalidated by the analysis.
