Reducing the time required for DNA analysis in forensic genetics can yield significant benefits, both in determining genealogical relationships for legal proceedings and in criminal cases. Swift identification of individuals plays a pivotal role in solving crimes and apprehending perpetrators. Additionally, in situations like mass disasters, prompt victim identification holds utmost importance. The Rapid DNA technology, introduced in 2012 to expedite DNA analysis, has evolved to streamline the process into a single step. This advancement not only minimizes the risk of human error and contamination, but also boasts a remarkable time advantage, delivering results in as little as 90 min. In this study, DNA profiles of 30 families (consisting of mothers, fathers, and children) were analyzed using the RapidHITTM ID System. The system automatically calculated maternity-paternity probabilities to assess the suitability of Rapid DNA technology for kinship analysis. For validation, DNA profiles were also generated using the 3500 GA method. The study revealed that 9 out of 30 families exhibited discrepancies in DNA profiling, leading to inaccuracies in automatic kinship analysis. Consequently, while the method offers rapid and user-friendly advantages for forensic sciences, the software underlying the system requires re-evaluation. Issues such as maternal-paternal exclusion in kinship analyses, arising from challenges like un-called alleles, warrant further attention.
缩短法医遗传学中DNA分析所需的时间可带来显著益处,无论是在法律程序中确定亲属关系还是在刑事案件中。迅速识别个体在破案和抓捕罪犯方面起着关键作用。此外,在大规模灾难等情况下,迅速识别受害者至关重要。2012年推出的快速DNA技术旨在加快DNA分析,现已发展到将该过程简化为一个步骤。这一进展不仅将人为错误和污染的风险降至最低,而且具有显著的时间优势,只需90分钟就能得出结果。在本研究中,使用RapidHITTM ID系统分析了30个家庭(由母亲、父亲和孩子组成)的DNA图谱。该系统自动计算亲子概率,以评估快速DNA技术在亲缘关系分析中的适用性。为了进行验证,还使用3500 GA方法生成了DNA图谱。研究发现,30个家庭中有9个家庭的DNA图谱存在差异,导致自动亲缘关系分析出现不准确情况。因此,虽然该方法为法医学提供了快速且用户友好的优势,但该系统的底层软件需要重新评估。亲缘关系分析中诸如因未检出等位基因等挑战导致的父母排除等问题值得进一步关注。
