Abstract
The gene defect responsible for X-linked lymphoproliferative syndrome, SH2D1A (SH2-domain-containing gene 1A), was recently cloned. This gene encodes a small protein of 128 amino acids containing a single SH2 domain, which is thought to play an important role in signal transduction in activated T cells. The definition of SH2D1A protein function will provide insight into the pathogenesis of fatal Epstein-Barr virus infection, lymphomas, Hodgkins disease, immunodeficiency, aplastic anemia and lymphohistiocytic disorders that characterize the syndrome.
