Here you are: IMGT Web resources > IMGT Repertoire (IG and TR) > 1. Locus and genes

"+" 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.

MAP: Mapped reference sequences.

IMGT notes:
  1. (1) frameshift in L-PART1 and frameshift in V-REGION: deletion of 1 nt in FR3-IMGT
  2. (2) No INIT-CODON.
  3. (3) No INIT-CODON and STOP-CODON in V-REGION.
  4. (4) STOP-CODON in V-REGION.
  5. (5) frameshift in V-REGION.
  6. (6) functionality defined for the available sequence of the gene (partial V-REGION in 5' because of gaps in the sequence).
  7. (7) noncanonical DONOR-SPLICE and noncanonical V-NONAMER.
  8. (8) noncanonical V-NONAMER.
  9. (9) no L-PART1, frameshifts in V-REGION.
  10. (10) noncanonical DONOR-SPLICE, noncanonical V-HEPTAMER and noncanonical V-NONAMER.
  11. (11) no INIT-CODON, frameshifts in L-PART1.
  12. (12) no INIT-CODON, frameshift in L-PART1 and frameshifts in V-REGION.
  13. (13) truncated and degenerated pseudogene.
  14. (14) frameshift in L-PART1
  15. (15) frameshift in L-PART1, STOP-CODON in V-REGION: position 41 and 42
  16. (16) Positions in V-REGION
