During B lymphopoiesis, many recombinant mechanisms are involved allowing the synthesis of immunoglobulins. The immunoglobulins are composed of two heavy and light identical chains. Within the IGK locus, mechanisms allow the association of a gene fragment of variability Vκ and junction Jκ. This mechanism is called V (D) J recombination of immunoglobulin genes. Previous work by Prof. Brigitte Gubler identified atypical rearrangements associating two Vκ genes, called Vκ2-Vκ in samples from patients with pediatric ALL-B. During this thesis work, we continued this study by focusing on the physiological appearance of Vκ2-Vκ rearrangements in sorted cell populations of cord blood. We have identified these atypical rearrangements at a frequency of...
