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 signify the frequency of occurrences of a specific allele within sequence data. A single star () indicates that no instances of the allele have been identified in the literature. Two stars () indicate the discovery of one literature sequence containing the allele. If more than one literature sequence is found to contain the allele, it is designated with three stars (). In the Excel file, the stars are represented by the plus symbol (+).

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.

IMGT notes: ↑
  1. noncanonical J-NONAMER: gtctttgtc instead of gcttttgtg, however this X-GENE has been found rearranged
  2. no J-RS
  3. noncanonical J-NONAMER: acttcttgt instead of gcttttgtg, noncanonical J-HEPTAMER: cattgtg instead of cacagtg
