Part Description

LP111251-7   T-cell receptor excision circle
T cell receptor excision circles (TRECs) are formed as a byproduct of T cell receptor (TCR) generation in the thymus. Every T cell has a unique TCR, and formation of TCRs involves DNA rearrangement into different combinations of variable, diversity, and joining sequences. As these combinations are created, the remaining fragments of excised DNA form circular structures, or TRECs. The number of TRECs is proportional to T cell production, with low TREC numbers being an indicator of inadequate T cell production. In newborns, dried blood spot TREC analysis is used to screen for severe combined immunodeficiency as well as other disorders associated with low T cell counts, such as DiGeorge syndrome, trisomy 21, CHARGE syndrome, and congenital leukemia.
