Correspondence between IMGT gene names and clone names is available in Gene tables: Human (Homo sapiens)

Correspondence between the different gene nomenclatures

All the IMGT human IG and TR gene name have been approved by the HUGO Nomenclature Commitee in 1999 and entered in the Genome Database and into Entrez Gene at NCBI, USA.

Human IGKV genes are listed from 3' (top of the table) to 5' (bottom of the table).

Proximal V-CLUSTER
from 3' (top of left column) to 5' (bottom of left column)(1-3)
from 3' (bottom of right column) to 5' (top of right column)(1-3)

IMGT notes:
  1. (1) IGLV genes are designated by a number for the subgroup, followed by a dash and a number for the localisation from 3' to 5' in the locus [1-2].
  2. (2) Pseudogenes, which could not be assigned to subgroups with functional genes are designated by a roman number between parentheses, corresponding to the clans, followed by a dash and a number for the localisation from 3' to 5' in the locus. Clans comprise, respectively:
    • clan I: IGLV1, IGLV2, IGLV6 and IGLV10 subgroup genes, and pseudogenes IGLV(I)-20, -38, -42, -56, -63, -68 and -70
    • clan II: IGLV3 subgroup genes
    • clan III: IGLV7 and IGLV8 subgroup genes
    • clan IV: IGLV5 and IGLV11 subgroup genes, and pseudogenes IGLV(IV)-53, -59, -64, -65 and -66-1
    • clan V: IGLV4 and IGLV9 subgroup genes, and pseudogenes IGLV(V)-58 and -66
    • clan VI: pseudogenes IGLV(VI)-22-1 and -25-1
    • clan VII: pseudogene IGLV(VII)-41-1
