[[http://www.uniprot.org/uniprot/SH21A_HUMAN SH21A_HUMAN]] Defects in SH2D1A are a cause of lymphoproliferative syndrome X-linked type 1 (XLP1) [MIM:[http://omim.org/entry/308240 308240]]; also known as X-linked lymphoproliferative disease (XLPD) or Duncan disease. XLP is a rare immunodeficiency characterized by extreme susceptibility to infection with Epstein-Barr virus (EBV). Symptoms include severe or fatal mononucleosis, acquired hypogammaglobulinemia, pancytopenia and malignant lymphoma.<ref>PMID:11477068</ref><ref>PMID:9771704</ref><ref>PMID:11823424</ref><ref>PMID:10598819</ref><ref>PMID:11049992</ref><ref>PMID:11034354</ref><ref>PMID:11493483</ref><ref>PMID:14674764</ref><ref>PMID:15841490</ref><ref>PMID:16720617</ref>

Acts by blocking recruitment of the SH2-domain-containing signal-transduction molecule SHP-2 to a docking site in the SLAM cytoplasmic region. Mediates interaction between FYN and SLAMF1. May also regulate the activity of the neurotrophin receptors NTRK1, NTRK2 and NTRK3.
