"+" 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) Partial V-REGION: AA 1 to 55 are missing (no FR1-IMGT, no CDR1-IMGT and no FR2-IMGT).
  2. (2) INSERTIONs of 5 amino acids between positions 60 and 61 in CDR2-IMGT (60A, 60B, 60C, 60D and 60E).
  3. (3) Partial V-REGION: AA 1 to 49 are missing (no FR1-IMGT, no CDR1-IMGT and partial FR2-IMGT).
  4. (4) ORF because unusual V-HEPTAMER sequence: ACACGTG instead of CACAGTG.
  5. (5) Pseudogene because frameshift in FR3-IMGT.
  6. (6) ORF because unusual V-NONAMER sequence: AAAAAAAGG instead of ACAAAAACC.
