Recently, Proceedings of the National Academy of Sciences (PNAS), a top international journal, published a paper entitled “Mapping Allele with Resolved Carrier State of Robertsonian and Reciprocal translocation in human pre-implantation embryos”, with Dr. Xu Jiawei of ZZU as first author, Pro. Sun Yingpu of ZZU as corresponding author, and Pro. Xie Xiaoliang of Harvard University and Dr. Lu Sijia of Yikon Genomics as co-corresponding authors. The publication of the paper marks that the world’s first application of allele mapping identification technology, which appplies to accurate selecｔion translocation-free embryos, preventing chromosomal translocations to future generations, led by No.1 Affiliated Hospital of Zhengzhou University and developed by the joint team of Harvard University and Yikon Genomics, has been acknowledged around the world.(translator Song Gencheng)
