Description:
Protein tyrosine kinases (PTKs) play an integral role in T cell activation and differentiation. Defects in the Src-family PTKs in mice and in T cell lines have resulted in variable defects in thymic development and in T cell antigen receptor (TCR) signal transduction. Here, three siblings are described with an autosomal recessive form of severe combined immunodeficiency disease (SCID) in which ZAP-70, a non-Src PTK, is absent as a result of mutations in the ZAP-70 gene. This absence is associated with defects in TCR signal transduction, suggesting an important functional role for ZAP-70.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, A C -- Kadlecek, T A -- Elder, M E -- Filipovich, A H -- Kuo, W L -- Iwashima, M -- Parslow, T G -- Weiss, A -- AR-20684/AR/NIAMS NIH HHS/ -- GM39553/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Jun 10;264(5165):1599-601.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8202713" target="_blank"〉PubMed〈/a〉
