• MONDO:0010604: hemophilia B

Cross-species summary: Also called hemophilia B, factor IX deficiency or Christmas disease. This is one of the two X-linked bleeding disorders, haemophilia A being the other. The fact that these two disorders are X-linked in all species reported to date provides strong support for Ohno's suggestion that the X chromosome has been highly conserved throughout evolution.

Species in which this phene is found:
dog (Canis lupus familiaris)
domestic cat (Felis catus)
horse (Equus caballus)
pig (Sus scrofa)
