"+" or "-" indicates if the gene sequences have been found (+) or not been found (-) rearranged (R), transcribed (T) and/or translated into protein (Pr). Arbitrarily that information is shown on the first line of each gene when the data have been confirmed by several studies.

Functionality is shown between parentheses, (F) and (P), when the accession number refers to rearranged genomic DNA or cDNA and the corresponding germline gene has not yet been isolated.
Functionality is shown between brackets, [F] and [P], when the accession number refers to genomic DNA, but not known as being germline or rearranged.

IMGT notes:
  1. (1) Frameshift in CDR2-IMGT
  2. (2) frameshift in L-PART1, frameshift in V-REGION: several insertions and deletions and no V-RS
  3. (3) position of V-REGION
  4. (4) Canis lupus familiaris TRDV2 (new gene), the unique representative gene of the Canlupfam TRDV2 subgroup in IMGT000004 (CM000008.3), has been added between TRDV4 and TRDD1 in Locus representation (V. Nguefack Ngoune and M-P. Lefranc, 23/09/2020).
