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 (+).

Click on:
  • IMGT gene name to get the corresponding IMGT/GENE-DB entry (link).
  • IMGT allele name to see the corresponding Alignments of alleles (link).
  • Accession number to get the corresponding IMGT/LIGM-DB entry (link).
  • MAP: mapped sequences. Click to access GENE-DB «LOCALIZATION IN GENOME ASSEMBLIES» (link).
  • [number] to access the corresponding IMGT reference (popover).
  • (number) to see the corresponding IMGT note (popover).
Options:
  • You can show/hide columns (), download data () or put the table in fullscreen () using buttons.

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.

The hits to sequences other than IMGT000046 are given for completeness but information on the positions in the contig and chromosomal localization of these sequences should be taken with great caution owing to the uncertainties regarding the genome assembly, and to the difficulty of assigning genes due to the duplications in the IGL locus.
Several pairs of genes have high percentage of identity of their V-REGION, reaching 100% of identity for the functional IGLV1-52*01 and IGLV1-47*01 genes and for the pseudogenes IGLV1-53*01, IGLV1-48*01 and IGLV1-29*01, IGLV8-44*01 and IGLV8-27*01, and IGLV(IV)-42*01 and IGLV(IV)-30*01. Arbitrarily these sequences are assigned to the gene with the smallest number.
