"+" 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.

Rearranged (R) and transcribed (T) information are from Assignment of rearranged cDNAs and gDNAs to germline genes: Human TRGV.

IMGT notes:
  1. (1) X15269 [6] is the 5'UTR of TRGV1*01 (M12949). The two sequences overlap by 4 nucleotides including the INIT-CODON ATG.
  2. (2) STOP-CODON in the L-PART1.
  3. (3) Frameshift in V-REGION: deletion of 1 nt in FR3-IMGT.
  4. (4) Frameshift in V-REGION: deletion of 1 nt in FR3-IMGT at position 346-347at position 346-347.
  5. (5) Noncanonical DONOR-SPLICE: nct instead of ngt.
  6. (6) Absence of splicing of the V10 leader intron ([7,9]).
  7. (7) Absence of splicing of the V11 leader intron ([7,9]).
  8. (8) No 1st-CYS: Trp instead of Cys.
  9. (9) STOP-CODON in frame in V-REGION.
  10. (10) STOP-CODON in L-PART1, frameshifts in V-REGION.
  11. (11) Noncanonical V-NONAMER: gtggttgct instead of ctgaaaatc.
  12. (12) The sequence AF057177 (53151 bp) is included in AF159056 (nt 1-53151 of 140691 bp) and is not reported in this table to avoid redundancy. Both sequences start 5.8 kb upstream of TRGV1. AF057177 ends 1.6 kb downstream of TRGVA, whereas AF159056 encompasses the entire locus and ends 6.8 kb downstream of TRGC2 EX3.
  13. (13) X15270 [6] is the 5'UTR of TRGV2*01 (M13429). The two sequences overlap by 4 nucleotides including the INIT-CODON ATG.
  14. (14) Polymorphic gene by insertion identified by Southern hybridization [11].
  15. (15) X15271 [6] is the 5'UTR of TRGV3*01 (M13430). The two sequences overlap by 4 nucleotides including the INIT-CODON ATG.
  16. (16) X15273 [6] is the 5'UTR of TRGV8*01 (M13434). The two sequences overlap by 4 nucleotides including the INIT-CODON ATG.
