"+" 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.

cDNAs have been included in this table as they are informative for the gene content of the corresponding genomic cassettes.

IMGT notes:
  1. (1) One V-GENE is in opposite orientation of transcription relative to that of one J-GENE and one C-GENE.
  2. (2) Two or three V-GENEs, one J-GENE and one C-GENE are in the same orientation of transcription.
