In the column 'Pseudogene', the number of pseudogenes with V-REGION in-frame and the number of pseudogenes with frameshift(s) are shown
separated by two dots, between parentheses.
* An asterisk indicates that there are genes that have alleles with different functionalities:
- FUNCTIONAL or PSEUDOGENE (IGLV4-60, IGLV6-57, IGLV10-54, IGLV9-49, IGLV7-46, IGLV3-22, IGLV3-12, IGLV3-9).
- ORF or PSEUDOGENE (IGLV11-55, IGLV5-48, IGLV1-41)
** Two asterisks indicate allelic polymorphisms by insertion/deletion
As seen in the
IGL Locus Representation IGLV genes are organised in three distinct
V-CLUSTERS, A, B and C.
Human (Homo sapiens) IGLJ genes
