Zusammenfassung: | Copyright © 2012 Elsevier Inc. All rights reserved. X-linked lymphoproliferative (XLP) disease is a primary immunodeficiency syndrome associated with the inability to control Epstein-Barr virus (EBV), lymphoma, and hypogammaglobulinemia. XLP is caused by mutations in the SH2D1A gene, which encodes the SLAM-associated protein (SAP), or in the BIRC4 gene, which encodes the X-linked inhibitor of apoptosis protein (XIAP). Here we report a patient with recurrent respiratory tract infections and early onset agammaglobulinemia who carried a unique disease-causing intronic loss-of-function mutation in SH2D1A. The intronic mutation affected SH2D1A gene transcription but not mRNA splicing, and led to markedly reduced level of SAP protein. Despite undetectable serum immunoglobulins, the patient's B cells replicated and differentiated into antibody producing cells normally in vitro |
