Abstract： In this study, arctic foxes Daxinganling region orexin gene structure features were analyzed through PCR-SSCP method to find the impact performance of arctic foxes orexin gene exon mutations. Data using SignalP 3.0 Server, ClustalX1.83, Mega4.0, Promoter predictions, TMHM2.0, ProtComp-v6.0 software and SPSS13.0 software such as biology to complete the analysis, the results of Arctic foxes and dogs genetic distance is the latest, by Orexin it may be a secreted protein with a signal peptide sequence is considerable, and orexin gene exon exists in many states, however, between genotypes no significant differences in type
