Gene Rearrangement, B-Lymphocyte, Light Chain
B Cell Light Chain Gene Rearrangement; B Cell kappa-Chain Gene Rearrangement; B Cell lambda-Chain Gene Rearrangement; B Lymphocyte Light Chain Gene Rearrangement; B Cell kappa Chain Gene Rearrangement; B Cell lambda Chain Gene Rearrangement
Ordered rearrangement of B-lymphocyte variable gene regions coding for the kappa or lambda light chains, thereby contributing to antibody diversity. It occurs during the second stage of differentiation of the immature B-lymphocyte.
