Involvement in diseasei

Immunodeficiency 7 (IMD7) [MIM:615387]: 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.
Note: The disease is caused by mutations affecting the gene represented in this entry.1 Publication

Miscellaneousi

Miscellaneous

This clone was isolated from a human leukemic T-cell line, Jurkat.
This alpha chain C region shows sequence homology to its beta chain counterpart.
The gene corresponding to this mRNA is rearranged specifically in T-cells; its organization is similar to an Ig gene, with V, D, J, and C regions.
