  • Title: Molecular biology of the Wiskott-Aldrich syndrome.
    Author: Rengan R, Ochs HD.
    Journal: Rev Immunogenet; 2000; 2(2):243-55. PubMed ID: 11258421.
    Abstract:
    The Wiskott-Aldrich syndrome (WAS) is an X-linked primary immunodeficiency associated with thrombocytopenia, bloody diarrhea, eczema, recurrent infections, and a high incidence of malignancies. X-linked thrombocytopenia (XLT) is a milder form with predominant platelet abnormalities. Both are caused by mutations of the cytoplasmic WAS protein (WASP). To date, mutations of WASP have been identified in over 340 families and consist of missense and nonsense mutations, deletions and insertions, and splice site mutations. There is a striking correlation between phenotype and genotype. The complex gene product of WASP has multiple functional domains that contribute to actin polymerization, cell motility, intracellular signaling, and apoptosis. Understanding the molecular basis of WAS/XLT not only explains the highly variable clinical phenotype, but also affects the medical management of this serious congenital disorder.
