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 sequences.

IMGT notes:
  1. (1) unexpected V-SPACER length: 9 nt instead of 23 nt
  2. (2) frameshift in L-PART1, frameshifts in V-REGION: several insertions and deletions
  3. (3) frameshift in V-REGION: deletion of 1 nt in FR1-IMGT
  4. (4) frameshift in V-REGION: deletion of 1 nt in FR3-IMGT
  5. (5) no INIT-CODON: Val instead of Met, STOP-CODON in V-REGION: position 15
  6. (6) no INIT-CODON: Val instead of Met, STOP-CODON in V-REGION: position 15
  7. (7) noncanonical V-HEPTAMER: cacagca instead of cacagtg, noncanonical V-NONAMER: tcaataaat instead of ctgaaaatc
  8. (8) noncanonical V-HEPTAMER: caccata instead of cacagtg
  9. (9) no INIT-CODON: Lys instead of Met, STOP-CODON in L-PART1, STOP-CODON in V-REGION: position 20, frameshifts in V-REGION: several insertions and deletions
  10. (10) no L-PART1
  11. (11) positions of V-REGION
  12. (12) no INIT-CODON: Cys instead of Met
  13. (13) STOP-CODON at position 109 (last 3' codon of germline CDR3-IMGT) may disappear during rearrangements
