1. A2143G位点 针对具体的突变位点,对比试验结果显示:A2143G位点测序检出突变阳性456 例,突变阴性 688 例,两种检测方法阳性符合率为 100%( 95%CI:99.16%～ 100%),阴性符合率为 97.97%( 95%CI:96.61%～98.78%),总符合率 98.78%( 95%CI:97.96%～ 99.27%)。
A significant difference was found between the 0–5- and 5–18-year-old groups in terms of the A2143G and A2142G point mutations (p = 0.001). The A2142C mutation was not detected. There was a significant difference in the A2143G mutation between the symptomatic and asymptomatic 5–18...
