IMGT Repertoire (IG and TR)


Gene table: human (Homo sapiens) IGHC

"+" or "-" indicates if the gene sequences have been found (+) or not been found (-) 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.

c: cDNA sequence.
(s): Transcript of a secreted chain.

IMGT notes:
  1. (1) In the IGHA gene, the hinge (H) and the CH2 are joined in a single exon.
  2. (2) Partial C-GENE: partial CH2 in 3'.
  3. (3) Partial C-GENE: partial H-CH2 in 5'.
  4. (4) Sequence assigned arbitrarily and temporarily to allele*01 in the absence of cDNA and complete genomic sequence.
  5. (5) Partial C-GENE: partial CH1 in 5' and partial CH2 in 3'.
  6. (6) Partial C-GENE: partial CH1 in 3'.
  7. (7) Partial C-GENE: partial CH2 in 3'.
  8. (8) Partial C-GENE: partial CH2 in 5' and partial CH3 in 3'.
  9. (9) Partial C-GENE: partial CH3 in 5'.
  10. (10) Partial C-GENE: partial CH4 in 5'.
  11. (11) DELETION of 3 bp in the CH3 which does not alter the open reading frame. The lack of SWITCH region seems to be the only defect responsible for the absence of protein.
  12. (12) DELETION of CH2 and CH3, DELETION of 3 bp in the ACCEPTOR-SPLICE of the CH3 leading to frameshifts.
  13. (13) Partial C-GENE: partial CH3 in 5' and 3'.
  14. (14) Partial C-GENE: partial CH4 in 5' and 3'.
  15. (15) Complete serological G3m typing: G3m(5,10,11,13,14,26,27) or G3m(b0,b1,b3,b4,b5,u,v); 5*=5,10,11,13,14 and b*=b0,b1,b3,b4,b5.
  16. (16) LAT IV-5 is homozygous for Gm(6,24*;1,17;..) and Gm(27,28) -or homozygous for Gm(b0,b1,c3,c5,u) and Gm(g5,v)- by study of this family [Lefranc G. et al., Hum. Genet., 50, 199-211 (1979)]; 6,24*=5,6,11,24,26.
    In the LAT IV-5 haplotype, the allotypes Gm27 and 28 have been shown to be be carried by the constant region of the IGHG1 gene. This Gm distribution has been found in other individuals with the same haplotype from African populations [Van Loghem, E. et al., Vox Sanguinis, 43, 301-309 (1982)].
  17. (17) Although the serological typing has not be done, the sequence encodes the Ser 212 (TCC) which corresponds to the A2m(2) allotype[14]. The EcoRI site which allows A2m(2) allotype determination by restriction fragment length polymorphism[14] is present.
  18. (18) The number of IGHG3 hinge exons is:
    • four exons in the most frequent alleles (IGHG3*01[17] and IGHG3*02[10])
    • three exons in allele IGHG3*03[18]
    • two exons in allele IGHG3*04[29]
  19. (19) J00228 corresponds to [5] (and not to [10], as indicated in the J00228 flat files. The correction has been asked to EMBL in December 1999).
  20. (20) Note that Ala 126 (225) (GCA) in Kabat Entry number 013486 is probably a typing error. The corresponding codon in the IMGT IGHG1 allele alignment is Val 98 (GTT), which is the last codon of the CH1 exon (and not the first codon of the hinge as shown in Kabat 013486). The IGHG1 Chimpanzee CH1 3' end is therefore identical to the human one, and Figure 3 and Discussion in Ehrlich P.H. et al., Molecular Immunology, 28, 319-322 (1991) should be revised accordingly. Comments added by M.-P. Lefranc on the 16/12/1999, following a question asked by M. Cerutti (France).
  21. (21) Z49802 previously described as a IGHG2*03 allele due to a289>g, g291>a, T97>A in CH3 is now considered as a IGHG2*01 allele, following the EMBL update of 20 september 1999 (a289, g291, T97).
  22. (22) The IGHG3 exon genomic organization of this allele is similar to that of the IGHG3*01 allele. The sequence encompasses CH1, H1, H2, H3 H4, CH2 and CH3 exons. The M1 and M2 exons were not sequenced.
  23. (23) The IGHG3 exon genomic organization of this allele is similar to that of the IGHG3*03 allele. The sequence encompasses CH1, H1, H3 H4, CH2 and CH3 exons. The M1 and M2 exons were not sequenced.
  24. (24) The CH2 Met 45.1 (ATG) has been shown to correlate with IGHG2 gene encoding the G2m(23) allotype [27]. In this paper the CH1 was not sequenced. More recently CH1 Thr 92 (ACC) has also shown to correlate with IGHG2 gene encoding the G2m(23) allotype [35].
  25. (25) Although the serological typing has not been done, the sequence encodes the CH2 Val 45.1 (GTG) which correlates with the absence of the G2m(23) [39].
  26. (26) Partial C-GENE: No CH1.
  27. (27) Partial C-GENE: partial CH3 in 3'.
  28. (28) Frameshift in CH3-CHS.
  29. (29) GenBank AH005273.2 (12223 bp) is an artificial assembly replacing AH005273.1 (J00230, V00554), J00221.1, J00222.1, J00230.1 (V00554), K01316.1, K01317.1, K01318.1, K01319.1 and V00554 (Aug 1. 2016). AH005273.2 has been entered in IMGT/LIGM-DB for completeness but, to avoid redundancy, is not an 'IMGT/LIGM-DB sequence from the literature'. Indeed, the seven individual accession numbers are in IMGT/LIGM-DB, and four of them are original IMGT reference sequences: J00230 (IGHG2*01), K01316 (IGHG4*01), J00222 (IGHE*01) and J00221 (IGHA2*01).
  30. (30) Identical sequence with IGHG4A*01.
