Chromosome 1 abnormality is one of the most common cytogenetic findings in MM (Multiple myeloma). A major feature of B cell malignancies is the slow increase in malignant plasma cells grown in the bone marrow. The CKS1B gene is located at 1q21 of chromosome 1 long arm end. In the progression of myeloma disease, tandem repetition and skip translocations of the 1q21 band occur, whereas in patients with multiple myeloma, 1q amplification is associated with poor prognosis.
PROBE DESCRIPTION
1q21 gene amplification detection probe uses an orange-red fluorescent label 1q21 region, and the 1q21 probe binds to the target detection site by in situ hybridization. This method is used to detect abnormalities of multiple myeloma genes, and provide clinical reference for the differentiation, prognosis and medication for leukemia patients.
CLINICAL SIGNIFICANCE
1q21 (CKS1B) is the most common genetic abnormality in MM. The expansion of CKS1B gene leads to the up-regulation of cell cycle, which causes many proliferative diseases. 1q21 amplification is often associated with MM phenotype infiltration, poor prognosis and rapid disease progress.
