    • The present invention relates to the detection of a cell proliferative disorder associated with alterations of microsatellite DNA in a sample. The microsatellite DNA can be contained within any of a variety of samples, such as urine, sputum, bile, stool, cervical tissue, saliva, tears or cerebral spinal fluid. The invention is a method to detect an allelic imbalance by assaying microsatellite DNA. Allelic imbalance is detected by observing an abnormality in an allele, such as an increase or decrease in microsatellite DNA which is at or corresponds to an allele. An increase can be detected as the appearance of a new allele. In practicing the invention, DNA amplification methods, particularly polymerase chain reactions, are useful for amplifying the DNA. DNA analysis methods can be used to detect such a decrease or increase. The invention is also a method to detect genetic instability of microsatellite DNA. Genetic instability is detected by observing an amplification or deletion of the small, tandem repeat DNA sequences in the microsatellite DNA which is at or corresponds to an allele. The invention is also a kit for practicing these methods.
    • 本发明涉及与样品中微卫星DNA的改变相关的细胞增殖性病症的检测。 微卫星DNA可以包含在各种样品中,例如尿液,痰液,胆汁,粪便,宫颈组织,唾液,眼泪或脑脊髓液中。 本发明是通过测定微卫星DNA检测等位基因不平衡的方法。 通过观察等位基因的异常来检测等位基因不平衡,例如与等位基因处于或对应的微卫星DNA的增加或减少。 可以检测到增加作为新等位基因的出现。 在实施本发明时,DNA扩增方法,特别是聚合酶链式反应,可用于扩增DNA。 DNA分析方法可用于检测这种减少或增加。 本发明也是检测微卫星DNA遗传不稳定性的方法。 通过观察微卫星DNA中位于或对应于等位基因的小的串联重复DNA序列的扩增或缺失来检测遗传不稳定性。 本发明也是用于实施这些方法的试剂盒。
