Gene therapy for the hemophilias

Abstract

The hemophilias are a group of severe bleeding disorders resulting from the lack of functional blood coagulation factor VIII (hemophilia A) or factor IX (hemophilia B). Factor IX, when activated, catalyzes the conversion of factor X to its activated form, and activated factor VIII serves as a cofactor in this reaction. Clinically the disorders are indistinguishable, and they were not distinguished in the laboratory until the 1950s, when two research teams independently demonstrated that plasma from one group of patients could correct the clotting defect of the other group (1, 2). Clinically the disease is characterized by frequent spontaneous bleeds into joints and soft tissues, with the potential to result in a chronic and debilitating arthropathy. More serious complications, and death, can result from bleeding into other critical closed spaces, such as the intracranial or the retroperitoneal space. The disease is classified as severe, moderate, or mild, based on circulating-factor levels, with severe defined as <1% of normal activity, moderate as 1–5%, and mild as 5–30%.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
