September 25th, 2024.

Bibliographical references in alphabetic order, small design changes and addition of "NL" for non-localized gene.

September 20th, 2023.

Implementation of the dynamic gene table.

Gene table legend:

"+" 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 in 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.

IMGT allele confirmation: A scoring system is employed to indicate the number of IMGT/LIGM-DB reference sequences and other sequences from the literature in which an IG or TR gene allele has been identified and annotated.

Removed genes/alleles
If a gene/allele existence or name has to be changed, the old name or gene/allele would be deleted and its name won't be reused. They are kept in the gene table for historical reasons.
A single star ()
indicates that an IG or TR gene allele is annotated in the reference sequence only.
Two stars ()
indicate that an IG or TR gene allele is annotated in its reference sequence and in one sequence from the literature.
Three stars ()
indicate that an IG or TR gene allele is annotated in its reference sequence and in at least two sequences from the literature.
In the Excel file, the stars are represented by the plus symbol (+).

IMGT notes:
  1. STOP-CODON in J-REGION
  2. noncanonical J-MOTIF: FAXG instead of FGXG
  3. noncanonical J-NONAMER: tgattttgc instead of ggtttttgt, unexpected J-SPACER length: 8 nt instead of 12 nt, noncanonical J-HEPTAMER: agatgtg instead of cactgtg
  4. no J-PHE: STOP-CODON instead of Phe
  5. frameshift in J-REGION: insertion of 2 nt causing defectuous DONOR-SPLICE
  6. noncanonical J-MOTIF: LGXE instead of FGXG
  7. noncanonical J-HEPTAMER: tattgtg instead of cactgtg
  8. the first codon of the germline J-REGION is a STOP-CODON which may disappear during rearrangements
  9. noncanonical DONOR-SPLICE: nct instead of ngt
  10. frameshift in J-REGION causing defectuous DONOR-SPLICE
