A new method called structural variation sequencing (SVseq), developed in China, offers a more comprehensive view of the human genome than current genetic tests. Traditional tests fragment DNA, making it difficult to detect large structural changes like duplications or inversions. SVseq, however, reads longer DNA segments, allowing for precise identification of the location, orientation, and breakpoints of these variations. A study using SVseq on 26 pregnancies successfully clarified the nature of extra DNA fragments, revealing that in two cases, the disruption of critical genes led to disease in the children. AI
