Nomenclature of the Human T Cell Receptor Genes

The human T cell receptors (TcR) alpha-beta and gamma-delta are the products of four sets of genes on two chromosomes: T cell receptors alpha (TRA) and delta (TRD) on chromosome 14 at 14q11.2, T cell receptor beta (TRB) on chromosome 7 at 7q35, and T cell receptor gamma (TRG) on chromosome 7 at 7p15-p14. This appendix presents tabulated lists of the human TcR alpha, beta, gamma, and delta genes named in accordance with the International ImMunoGeneTics database and approved by the Human Genome Organization Nomenclature Committee in 1999. Two additional tables list corresponding nomenclatures for these genes.
