Table of alleles: Human IGKJ

IMGT numbering and description of alleles for germline J-REGIONs start with the first nucleotide of the first codon. The accession number of a reference sequence is given for each allele.

Click on a gene name to get the alignment of the corresponding J-REGION alleles.
Click on an accession number to get the sequence and additional information (IMGT annotations, IMGT flat file, Coding regions...).

Rearranged genomic or cDNA have been included in the Alignments of alleles and Tables of alleles when several sequences from independent sources have been found with the same mutations. These alleles need to be confirmed by complete germline genomic sequences.
