The molecular basis of X-linked immunodeficiency disease

Abstract

The molecular bases of the X-linked immunodeficiency diseases remain largely undetermined. Two of the genes involved in these diseases have been isolated, namely the genes for X-linked chronic granulomatous disease and properdin deficiency, and substantial progress has now been made in identifying the genes which are defective in the other five diseases, Wiskott-Aldrich syndrome, X-linked severe combined immunodeficiency, X-linked agammaglobulinaemia, X-linked hyper-IgM and X-linked lymphoproliferative syndrome. We review here the nature of the diseases, progress made in identifying and isolating the genes involved and the prospects for improved prenatal detection, carrier status determination and treatment of these life-threatening conditions.
