Genes of the human TR loci belong to fourteen groups

• The human TRA locus at 14q11.2 comprises genes belonging to three groups: TRAV, TRAJ and TRAC [1].
• The human TRB locus at 7q34 comprises genes belonging to four groups: TRBV, TRBD, TRBJ and TRBC [1].
• The human TRG locus at 7p14 comprises genes belonging to three groups: TRGV, TRGJ and TRGC [1].
• The human TRD locus at 14q11.2 comprises genes belonging to four groups: TRDV, TRDD, TRDJ and TRDC [1].
