"+" 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) deletions in V-REGION: 4 AA are missing in FR3-IMGT, unexpected V-SPACER length: 27 nt instead of 23 nt
  2. (2) frameshift in V-REGION: deletion of 1 nt in FR1-IMGT
  3. (3) frameshifts in V-REGION: several insertions and deletions in V-REGION
  4. (4) no INIT-CODON: Leu instead of Met, frameshift in V-REGION: insertion of 1 nt in FR2-IMGT
  5. (5) STOP-CODON at position 108 (last 3' codon of germline CDR3-IMGT) may disappear during rearrangements
  6. (6) no DONOR-SPLICE
  7. (7) no INIT-CODON: Leu instead of Met, STOP-CODON in L-PART1, no DONOR-SPLICE, frameshifts in V-REGION: several insertions and deletions in V-REGION

  9. (9) no CONSERVED-TRP: Gly instead of Trp
  10. (10) STOP-CODON in V-REGION: positions 6 and 108, frameshifts in V-REGION: several deletions
  11. (11) STOP-CODON in V-REGION: positions 44 and 109
  12. (12) STOP-CODON in V-REGION: positions 6 and 108
  13. (13) no DONOR-SPLICE, frameshifts in V-REGION: several insertions and deletions in V-REGION, no V-RS
  14. (14) Positions of V-REGION
