The chromosome number in the corresponding genome is provided. Dashed lines correspond to regions of break of synteny. Abbreviations: , Homo sapiens; , Pan troglodytes; , Macaca mulatta; , Mus musculus; , Rattus norvegicus; , Gallus gallus. . Since for chimp and macaque no mRNA sequences are available, the human and were used as templates for gene predictions. In chimp, the intron putatively gained by is composed of eight repeats. In the genomic regions corresponding to chimp , there are four additional Zn-Fingers, which are reported in black because there is no evidence for their transcription. The dashed lines represent regions of gaps in the genome assembly. In rodents, the last intron is longer and not in scale; the corresponding length is reported in brackets. . The grey lines represent the genomic regions of segmental duplication. The corresponding chromosome number, chromosomal coordinates and direction of transcription are given. For , the splicing variants present in the database are shown. For , both the database transcripts and the isoforms detected in this study are reported together with an in-silico gene prediction obtained by using the PRDM9 long isoform as template.
