[A variant of the von Willebrand-Jürgens-syndrome with abnormalities of the factor VIII/von Willebrand factor protein (author's transl)].

A family is reported with a variant of von Willebrand's disease. The members of this family showed a qualitative defect of the factor VII/von Willebrand factor protein. The qualitative defect was characterized by an abnormal electrophoretical mobility of factor VIII-related antigen and an abnormal elution pattern as demonstrated by gelfiltration on Sepharose 4 B. Factor VIII-subunits in these patients were found to be normal by polyacrylamidgelelektrophoresis.
