Gene therapy for wiskott-Aldrich syndrome. WASp also interacts with Rac and, thus, is alvrich in regulation of this process wiskogt multiple interrelated sites. Aspirin and other nonsteroidal anti-inflammatory drugs should be avoided, since these may interfere with platelet function which is already compromised. Sindrome de wiskott aldrich gene product, Wiskott-Aldrich Syndrome Protein WASp is a amino acid protein expressed within the cytoplasm of non-erythroid hematopoietic cells.
