Summaries for CD3G Gene

Entrez Gene Summary for CD3G Gene

  • The protein encoded by this gene is the CD3-gamma polypeptide, which together with CD3-epsilon, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. Defects in this gene are associated with T cell immunodeficiency.

GeneCards Summary for CD3G Gene

CD3G (CD3g Molecule) is a Protein Coding gene. Diseases associated with CD3G include Immunodeficiency 17, Cd3 Gamma Deficient and Immunodeficiency Due To Defect In Cd3-Gamma. Among its related pathways are CXCR4-mediated signaling events and HTLV-I infection. GO annotations related to this gene include protein heterodimerization activity and receptor signaling complex scaffold activity. An important paralog of this gene is CD3D.

  • Immunodeficiency 17 (IMD17) [MIM:615607]: An autosomal recessive primary immunodeficiency characterized by highly variable clinical severity. Some patients have onset of severe recurrent infections in early infancy that may be lethal, whereas others may be only mildly affected or essentially asymptomatic into young adulthood. More severely affected patients may have evidence of autoimmune disease or enteropathy. The immunologic pattern is similar among patients, showing partial T-cell lymphopenia, decreased amounts of the CD3 complex, and impaired proliferative responses to T-cell receptor dependent stimuli. The phenotype in some patients is reminiscent of severe combined immunodeficiency. {ECO:0000269 PubMed:1635567, ECO:0000269 PubMed:17277165}. Note=The disease is caused by mutations affecting the gene represented in this entry.
