"+" 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.

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.
