More information:
  1. Gene and allele table: Mouse (Mus musculus) IGHC
  2. Protein display: Mouse (Mus musculus) IGH C-REGIONs
IMGT notes:
(1) Only allele *01 is shown.
(2) Position of the last complete codon of the 5' exon and that of the first complete codon of the 3' exon are according to the IMGT unique numbering for C-DOMAIN and C-LIKE-DOMAIN.
(3) The last nucleotide G of the IGH J-REGION, part of the codon resulting from the splicing with CH1, is indicated for each IGHC gene.
(4) The donor splice of the 5' exon is an internal donor splice (INT-DONOR-SPLICE) involved in the splicing of the IGH membrane chain transcript. Synthesis of a membrane and of a secreted immunoglobulin mu heavy chain (IMGT Education)
(5) Defined by homology with the other IGHG2 genes. Needs to be confirmed by sequencing.
