Therapeutic Antibodies Against Prion Diseases From PRNP Mutation Carriers (PRNP)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02837705

Brief Summary:
The human Prion diseases can be classified into sporadic, acquired and inherited forms. Inherited forms usually manifest in higher age so there have to be factors preventing Prion propagation in young mutation carriers. Antibodies against the flexible tail of Prions have been shown to be protective in mice. The investigators intend to screen mutation carriers and controls for the presence of Prion autoantibodies.
