The interspecies subgroups were named after the human subgroup, and the novel bovine subgroups (subgroups without human members) were named after the member with the lowest number. The total number of bovine and human genes in each subgroup is listed, as well as the total number of V genes in the locus
Ψ pseudogene
aIncomplete sequence
bThis subgroup consists of one TRAV and one TRAV/DV
cBovine TRDV1 and human TRDV1 subgroups can be considered to form one interspecies subgroup because human TRDV1 is >75% identical to multiple bovine TRDV1 genes. However, this does not hold for all bovine TRDV1 genes
dHuman TRDV3 is homologous to bovine TRDV4 and form an interspecies subgroup based on >75% identity at the nucleotide level
