Citing this page: Barbié, V. and Lefranc, M.-P., Exp. Clin. Immunogenet., 15, 171-183 (1998) PMID: 9813414 pdf UPDATE: Human IGKV (04/2005)

"+" 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 7 human (Homo sapiens) IGKV subgroups belong to three clans (Figure IGKV clans). Clans comprise, respectively:

IGKV gene names are designated by a number for the subgroup, followed by a dash and a number for the localization from 3' to 5' in the locus. The IGKV genes of the distal duplicated V-CLUSTER are designated by the same number as the corresponding genes in the proximal V-CLUSTER, with the letter D added.

IMGT notes:
  1. (1) Based on a 21 bp DELETION starting at nucleotide 4 of DECAMER [11], the IGKV1-8 functionality was initially defined as "ORF". However the identification of several transcripts indicated that the IGKV1-8 gene is functional (Stamatopoulos K., Belessi C. and Lefranc M. P. 10/10/2007).
  2. (2) TTTGCTT instead of TTTGCAT in the core sequence of the DECAMER element [11], but transcript found [8].
  3. (3) CONSERVED-TRP replaced by a STOP-CODON in FR2-IMGT, and non canonical V-HEPTAMER: CATAGTG instead of CACAGTG [11].
  4. (4) STOP-CODONs in FR2-IMGT, INSERTION of 4 bp at position 72 leading to a frameshift in FR3-IMGT [11].
  5. (5) Non canonical V-HEPTAMER: CACTGTG instead of CACAGTG [33], but rearrangement products and productive cDNA found ([8] and see IMGT/GENE-DB).
  6. (6) DELETION of 2 bp at position 17 and INSERTION of 1 bp at position 27/28, 1 bp at position 87/88, and 3 bp at position 85, leading to frameshifts [11]
  7. (7) DELETION of nucleotide 4, and INSERTION of 1 bp at position 15/16. Defective DONOR-SPLICE [11].
  8. (8) STOP-CODON in L-PART1 [11].
  9. (9) IGKV1D-13*01, initially considered as an ORF, due to a non canonical V-HEPTAMER: CATAGTG instead of CACAGTG [11], has been found rearranged and transcribed in a 'productive' sequence (DQ101035). The sequence was obtained from a CLL case expressing kappa light chain isotype (by flow); this case also carried a non-productive, non-transcribed rearranged of the IGKV2-29*01 pseudogene. On these grounds, the IGKV1D-13*01 rearrangement was considered as expressed. (message from K. Stamatopoulous and C. Belessi to M.-P. Lefranc, 07/04/2008).
  10. (10) INSERTION of 1 bp at position 57 in FR3-IMGT, leading to a frameshift [11].
  11. (11) DELETION of 2 bp at position 17, INSERTION of 1 bp between codons 27/28, INSERTION of 3 bp in codon 85, INSERTION of 1 bp between codons 87/88 [11].
  12. (12) TTTGCTT instead of TTTGCAT in the core sequence of the DECAMER, and altered V-HEPTAMER: CACAGGG instead of CACAGTG [11].
  13. (13) No INIT-CODON: ATG replaced by GTG [11].
  14. (14) DELETION of 1 bp at position 74 leading to a frameshift, no INIT-CODON: ATG replaced by GTG, and non canonical ACCEPTOR-SPLICE [11].
  15. (15) No INIT-CODON: ATG replaced by GTG , CT instead of GT in ACCEPTOR_SPLICE, and DELETION of 1 bp at position 4 leading to a frameshift, and non canonical V-HEPTAMER [11].
  16. (16) No INIT-CODON: ATG replaced by ATA [11].
  17. (17) No Vk-gene related sequence was found upstream of codon 12, 5' part of V-REGION truncated [11].
  18. (18) V-EXON consists of 2 parts, separated by 180 bp that show no homology to Ig genes. STOP-CODON at position 35, and no INIT-CODON: ATG replaced by GTG [11].
  19. (19) Frameshift in FR2-IMGT due to 1 bp INSERTION at position 39, and non canonical V-NONAMER [11].
  20. (20) STOP-CODON at position 88 in FR3-IMGT [11].
  21. (21) STOP-CODONs in V-REGION, V-REGION truncated: breakoff of homology before codon 15 and after codon 87 [11].
  22. (22) STOP-CODONs in V-REGION, and breakoff of homology before codon 21, and STOP-CODON in V-REGION [11].
  23. (23) No Vk-gene related sequence was found upstream of codon 12, 5' part of V-REGION truncated [11].
  24. (24) V-EXON consists of 2 parts, separated by 180 bp that show no homology to Ig genes, STOP-CODON in FR2-IMGT, and no INIT-CODON [11].
  25. (25) INSERTION of 1 bp in codon 45 (134^135>ins^a) and DELETION of 1 bp in codon 51 (g153>del) [11]. The insertion in codon 45 leads to a frameshift but the normal reading frame is reestablished by the deletion in codon 51. The resulting sequence shows six amino acid changes from codon 46 to 51 in the FR2-IMGT. The frameshift originally described in FR1-IMGT [13] has not been confirmed.
  26. (26) IGKV2D-29*02, initially considered as an ORF due to a non canonical V-HEPTAMER: CACAGAG instead of CACAGTG, has been found rearranged and transcribed in a 'productive' sequence (DQ101097).
  27. (27) GG instead of AG in the ACCEPTOR_SPLICE [11].
  28. (28) Heavily mutated, insertion of 1.2 kb in V-INTRON. INSERTION of: 3 bp in codon -14/13, 7 bp in codon 81, and DELETION of: 2 bp in codon 27A, 24 bp from codon 56 to 65, 1 bp in codon 83 [11].
  29. (29) STOP-CODON in L-PART1, and DELETION of 2 bp in codon 6 leading to a frameshift [11].
  30. (30) DELETION of 2 bp in codon 5 leading to a frameshift [33].
  31. (31) DELETION of 2 bp at position 6, leading to a frameshift [11].
  32. (32) STOP-CODON in FR1-IMGT and FR2-IMGT at positions 23 and 38, INSERTION of 1 bp at position 85/86 [11].
  33. (33) STOP-CODON in CDR3 in codon 94 [11].
  34. (34) STOP-CODON in L-PART1, and 2 bp DELETION at position 6 leading to a frameshift [11].
  35. (35) STOP-CODON in FR1-IMGT and FR2-IMGT at positions 23 and 38, INSERTION of 1 bp at position 85/86 [11].
  36. (36) Non canonical V-HEPTAMER: CACTGTG instead of CACAGTG [11].
  37. (37) No INIT-CODON: ATG replaced by ATA[11].
  38. (38) IGKV2nd-CYS replaced by a Glycine in FR3-IMGT.
  39. (39) IGKV4-1 is in an inverted orientation of transcription.
  40. (40) IGKV5-2 is in an inverted orientation of transcription.
  41. (41) IGKV1st-CYS replaced by a Phenylalanine in FR1-IMGT.
  42. (42) IGKV1-13*02, initially considered as an ORF, has been found rearranged and expressed in a functional anti-TPO sequence (clone TR1.9) (L12099) [38] (N. Chapal, S. Roux, T. Chardes and M.-P. Lefranc, comment, 9/11/2000). The Fab of that clone has been crystallized and its 3D structure determined (PDB: 1vge). Note that the four first amino acids ELVM of the V-REGION in L12099 and PDB: 1vge are introduced by the primer. The IgA1 theoretical model (PDB: 1iga) uses the 1vge sequence and structure for the kappa chain (M.-P. Lefranc comments, 28/09/2001)
  43. (43) In EMBL, a new accession number M27751 was created, the original accession number X12688 becoming secondary accession number of M27751.
  44. (44) IGKV1-NL1 is most probably a polymorphic gene by insertion/deletion (found in 12 of 57 (21 %) healthy Caucasians) [40].
  45. (45) The most 3' nucleotide of L-PART2 of A18c is A instead of G. This allele is described as IGKV2-29*03 (L-PART2 g12>a) according to the IMGT numbering for coding regions.
  46. (46) It is not known if this sequence corresponds to that gene or to its duplicate. For that reason, the sequence appears twice in the IMGT/GENE-DB reference sequences.
  47. (47) In the absence of complete sequence the functionality ORF has been assigned based on the other alleles.
  48. (48) As the DPK sequences only contain the V-REGION, some of them could be assigned neither to a gene or its duplicate, nor to any allele of the gene.
  49. (49) Means that the rearrangement, transcript or protein could not be assigned to the gene in the proximal or distal cluster.
  50. (50) IGKV6-21*01, initially considered as an ORF, due to a non canonical V-HEPTAMER: CACTGTG instead of CACAGTG [11], has been found rearranged.
  51. (51) IGKV6D-21*01, initially considered as an ORF, due to a non canonical V-HEPTAMER: CACTGTG instead of CACAGTG [11], has been found rearranged.
  52. (52) The sequence FM164407 previously designated as IGKV1D-17*02 has been shown to correspond to allele IGKV1-17*03 (19/01/2015).
  53. (53) Chimeric sequence between IGKV3D-20 in 5', codons 1 to 106, and IGHV3D-11 in 3', codons 107 to 111, and absence of transcripts.
  54. (54) The sequence L19272 obtained by Polymerase Chain Reaction (PCR) has the features of a chimeric sequence between two different genes belonging to the Homo sapiens IGKV3 subgroup (IGKV3D-20 in 5', codons 1 to 106, and IGHV3D-11*02 in 3', codons 107 to 111). This sequence has been assigned to IGKV3D-20*02 allele with the functionality ORF (chimeric sequence and absence of identified transcripts). This assignment needs to be confirmed by analysis of other genomic and mapped germline clones. (M-P. Lefranc, IMGT-NC, 15/02/15)
