The chromatin unfolding assay showed that ,like the wild-type transactivation domain, two variants that represent benign polymorphisms did not induce chromatin unfolding or only induced subtle change. Contrary to the behaviors of the wild type and two benign variants, four cancer-predisposing mutations in the transactivation domain superactivate the chromatin unfolding. The results suggest that the chromatin unfolding assay can aid in the characterization of deleterious mutations in the C-terminal transactivation domain of BRCA1 and may provide more reliable presymptomatic risk assessment.

对这些重组质粒的染色质伸展活性检测表明，野生型pwt和两种良性多态性突变体不具有染色质伸展活性或只有极微弱的染色质伸展活性，而其他4种乳腺癌易感突变体均具有过强的染色质伸展活性，提示利用染色质伸展技术可预测BRCA1转录激活区基因型与乳腺癌发生风险的表现型的关系。

Results The positive cases of TTV-DNA were twenty-one in one hundred and thirty five aged viral hepatitis patients and the positive ratio was 15.6%; The TTV genic model was chief Ⅰ model （76.2%）, The TTV singleness infection cases were two （9.5%） yet the superposable infection ratio was 90.5%, the difference had prominence.

结果 135例老年病毒性肝炎患者中TTV-DNA阳性者21例，阳性率为15.6％；TTV基因型主要为Ⅰ型（76.2％），TTV单独感染仅2例（9.5％），重叠感染率达90.5％，两者差异具显著性（P〈0.01）。
