Gene rearrangement involves a complex process of DNA splicing and deletion that produces a unique genetic code in each B or T lymphocyte. These novel DNA sequences encode immunoglobulin or T-cell receptor proteins that function in recognition of foreign antigens. Recent advances in DNA technology permit laboratory detection of clonal gene rearrangements in lymphoid malignancies including lymphocytic leukemia, lymphoma, and myeloma. Practical applications of gene rearrangement testing include distinguishing reactive from malignant lymphoid proliferations, and assignment of B- or T-cell lineage to a neoplastic process. Active investigation is underway to devise practical strategies for detecting minimal residual disease based on tumor-specific gene rearrangements.

UI	MeSH Term	Description	Entries
D007938	Leukemia	A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.

D000906	Antibodies	Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).
D015139	Blotting, Southern	A method (first developed by E.M. Southern) for detection of DNA that has been electrophoretically separated and immobilized by blotting on nitrocellulose or other type of paper or nylon membrane followed by hybridization with labeled NUCLEIC ACID PROBES.	Southern Blotting,Blot, Southern,Southern Blot
D015322	Gene Rearrangement, B-Lymphocyte	Ordered rearrangement of B-lymphocyte variable gene regions coding for the IMMUNOGLOBULIN CHAINS, thereby contributing to antibody diversity. It occurs during the differentiation of the IMMATURE B-LYMPHOCYTES.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
