We have studied forty Chinese adult ALL patients at newly diagnosis, using standard primers and protocols of BIOMED-2 multiplex PCR, to determine the feasibility of Ig and TCR gene rearrangements as diagnostic and patient-specific MRD-RQ-PCR targets for molecular monitoring. Clonal IGH, IGK, IGL, TCRB, TCRG and TCRD rearrangements were found in 86%, 22%, 9%, 19%, 77%, 55% of adult patients with B-lineage ALL, respectively. While in T-ALL, clonal IGH, TCRB, TCRG and TCRD rearrangements were detected in 6%, 83%, 78%, 33% of patients. Several specialties in the pattern of Ig/TCR gene rearrangements in Chinese adult ALL patients in comparison with those reported for children and adult patients in other countries have been noted. These results are useful for further MRD-RQ-PCR detection and quantification for all patients.

D005803 Genes, Immunoglobulin Genes encoding the different subunits of the IMMUNOGLOBULINS, for example the IMMUNOGLOBULIN LIGHT CHAIN GENES and the IMMUNOGLOBULIN HEAVY CHAIN GENES. The heavy and light immunoglobulin genes are present as gene segments in the germline cells. The completed genes are created when the segments are shuffled and assembled (B-LYMPHOCYTE GENE REARRANGEMENT) during B-LYMPHOCYTE maturation. The gene segments of the human light and heavy chain germline genes are symbolized V (variable), J (joining) and C (constant). The heavy chain germline genes have an additional segment D (diversity).
