  • Title: The V kappa genes of the L regions and the repertoire of V kappa gene sequences in the human germ line.
    Author: Huber C, Schäble KF, Huber E, Klein R, Meindl A, Thiebe R, Lamm R, Zachau HG.
    Journal: Eur J Immunol; 1993 Nov; 23(11):2868-75. PubMed ID: 8223863.
    Abstract:
    Only 14 of the 25 V kappa genes and pseudogenes had been found before as parts of the L regions. The cloning and linking described in the accompanying report allowed us now to assign to Lp or Ld some V kappa genes which had been found before on scattered clones. In addition the sequences of several still unknown genes are reported here, thus completing the publication of the V kappa genes of the kappa locus as far as they are potentially functional or have only one or two 1-bp defects. Of the V kappa genes of the kappa locus, 32 are potentially functional, 16 have minor defects, 3 have both potentially functional and slightly defective alleles and 25 are pseudogenes which amounts to a repertoire of 76 V kappa-related gene sequences. The V kappa genes of the L regions are, within the subgroups, particularly similar to each other, which is in part due to common evolutionary origins and in part caused by gene conversion-like events. One donor-acceptor pair could be clearly identified, since converted and not-converted alleles of the acceptor gene were found. In other cases the duplicates of the converted genes served as non-converted controls.
