ABO blood group system (and Factor VIII) than do non-O individuals. In addition, vWF is degraded more rapidly due to the higher prevalence of blood group O with the Cys1584 variant of vWF (an amino acid polymorphism in VWF): the gene for ADAMTS13 (vWF-cleaving protease) maps to the ninth chromosome (9q34), the same locus as ABO blood type. Higher levels of vWF are more common amongst people who have had ischemic stroke (from blood clotting) for the first time. The results of this study found that the occurrence was not affected by ADAMTS13 polymorphism, and the only significant genetic factor was the person's blood
Jehovah's Witnesses and blood transfusions Jehovah's Witnesses and blood transfusions Jehovah's Witnesses believe that the Bible prohibits ingesting blood and that Christians should not accept blood transfusions or donate or store their own blood for transfusion. The belief is based on an interpretation of scripture that differs from that of other Christian denominations. It is one of the doctrines for which Jehovah's Witnesses are best known.
