Summaries for T-Cell Receptor-Alpha/beta Deficiency

UniProtKB/Swiss-Prot : 74 Immunodeficiency 7: A primary immunodeficiency disorder manifesting with recurrent respiratory infections, candidiasis, diarrhea, and failure to thrive. Patients show a clear predisposition to herpes viral infections, and features of immune dysregulation, including hypereosinophilia, vitiligo, and alopecia areata. Other features include lymphadenopathy and hepatosplenomegaly. CD3+ T-cells express TCR-gamma/delta, but little or no TCR-alpha/beta.

MalaCards based summary : T-Cell Receptor-Alpha/beta Deficiency, also known as immunodeficiency 7, tcr-alpha/beta deficient, is related to immunodeficiency, common variable, 7 and colitis. An important gene associated with T-Cell Receptor-Alpha/beta Deficiency is TRAC (T Cell Receptor Alpha Constant). Affiliated tissues include t cells, and related phenotypes are failure to thrive and autoimmunity
