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.

IMGT notes:
  1. (1) several STOP-CODON in V-REGION, frameshift in V-REGION: deletion of 2 nt in CDR3-IMGT
  2. (2) frameshift in V-REGION: deletion of 1 nt in FR3-IMGT
  3. (3) no CONSERVED-TRP: STOP-CODON instead of Trp, several STOP-CODON in V-REGION, frameshifts in V-REGION: deletion of 1 nt and deletion of 1 nt in FR3-
  4. (4) no INIT-CODON: Arg instead of Met, frameshifts in V-REGION: several insertions and deletions
  5. (5) frameshift in L-PART1: deletion of 1 nt causing defectuous DONOR-SPLICE
  6. (6) no L-PART1, truncated pseudogene not assigned to subgroups with functional genes, no V-NONAMER
  7. (7) Positions of V-REGION
  8. (8) frameshift in V-REGION: deletion of 4 nt in CDR1-IMGT, frameshift in L-PART1: deletion of 1 nt causing defectuous DONOR-SPLICE
