Gene Rearrangement, B-Lymphocyte, Heavy Chain

B Cell Heavy Chain Gene Rearrangement; B Cell Mu Chain Gene Rearrangement; B Lymphocyte Heavy Chain Gene Rearrangement; B Lymphocyte Mu Chain Gene Rearrangement
Ordered rearrangement of B-lymphocyte variable gene regions thereby contributing to antibody diversity. It occurs during the first stage of differentiation of the immature B-lymphocyte.
