Recent progress in molecular biology has led to a rapid expansion of our understanding of the proteins that are essential for hemostasis and thrombosis. The goal of the XXI Annual Scientific Symposium of the American Red Cross was to provide a forum to explore and document the impact of recombinant DNA technology in this field. The speakers described the essential features of the genes responsible for key plasma proteins important in hemostasis, including procoagulant Factors VIII and IX and anticoagulant proteins, Antithrombin III and Protein C. They emphasized the advances in recombinant DNA technology that have led to the cloning of these genes. Careful examination of the gene sequence has then provided a clearer understanding of the structure of the encoded proteins, and has given additional insight into their functional domains and their interactions in hemostasis. At the same time, these advances have made it possible to better characterize hemostatic disorders. A large number of published studies have shown that the mutations affecting biological activity are clustered in areas that define functional domains. They have led to fundamental advances in our understanding of specific diseases and they have made it possible to develop more accurate and sensitive diagnostic tests for the detection of the disease states.

"For the blood is the life . . . . "(Deut. 12 :23) " . . . because the blood, in its value as life, makes atonement" (Lev. 17: 11) HemoPhilia is a rare disease, severe hemophilia rarer still, yet the written history of hemophilia extends back over a millennium and a half. In the ancient Middle East, blood and life were coupled. Blood was the primary substance necessary for life, given to God in sacrifice and forbidden as a food to mortals by Levitical law. Blood was essential for rites of purification and consecration. But the flow of blood during menstruation or parturition rendered a woman unclean. The circumcision of a male child required 33 days of "blood purification" by the mother. ' Circumcision, the visible reminder of the covenant of Abraham lijith Yahweh, was required of newborn Jewish males. It "connote(d) suitability for participation in what God is doing. "2 Hence, free and uncontrolled bleeding of the male child during circumcision, during the ratification of God's covenant, would be noted with awe and concern by those of the Jewish faith. It should not be surprising that the first genetic counseling offered to families with hemophilia is found in the Babylonian Talmud (compilation of Jewish law dated to about the third century AD) and concerns the necessity for circumcision in families with what we would now call hemophilia.
