Program version: v. 

Add the possibility to obtain a gene table per strain (for mouse now and for other species later) and allotypes/isotypes for human.
September 25th, 2024.

Bibliographical references in alphabetic order, small design changes and addition of "NL" for non-localized gene.
June 14th, 2024.

Addition of 'Score for IMGT allele confirmation' as well as NCBI TPA accession numbers.
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.

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 (+).

Select a species and a IMGT group to get the gene table:
Only IMGT available species/group are shown in the drop-down list.
The gene table can take several seconds to appear, please be patient.
Some genes were declared functional because it has been found rearranged in specific sequences in Bioproject PRJNA939558.
