"+" 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) Non canonical J-REGION: Phe-Gly-X-Cys instead of Phe-Gly-X-Gly, non canonical J-HEPTAMER and defective DONOR_SPLICE.
  2. (2) Non canonical J-REGION: Phe-Val-X-Gly instead of Phe-Gly-X-Gly, non canonical J-HEPTAMER, non canonical J-NONAMER and defective DONOR_SPLICE.
  3. (3) Defective DONOR_SPLICE and non canonical J-HEPTAMER.
  4. (4) Non canonical J-REGION: Phe-Val-X-Gly instead of Phe-Gly-X-Gly, and non canonical J-HEPTAMER.
  5. (5) Frameshift due to three insertions of one nucleotide.
  6. (6) Temporary designation for not yet mapped TRA J-SEGMENT.
