B-Cell Gene Rearrangement
... B-cell lymphomas account for greater than 90% of non-Hodgkin lymphomas and may pose a diagnostic challenge on the basis of histopathology alone. During normal B-cell maturation, the immunoglobulin heavy chain gene is rearranged such that each mature B-cell and plasma cell has a unique rearranged hea ...
