    • ABSTRACT OF THE DISCLOSURE The invention provides a method for determining copy number variations (CNV) of a sequence of interest in a test sample that comprises a mixture of nucleic acids that are known or are suspected to differ in the amount of one or more sequence of interest. The method comprises a statistical approach that accounts for accrued variability stemming from process-related, interchromosomal and inter-sequencing variability. The method is applicable to determining CNV of any fetal aneuploidy, and CNVs known or suspected to be associated with a variety of medical conditions. CNV that can be determined according to the present method include trisomies and monosomies of any one or more of chromosomes 1-22, X and Y, other chromosomal polysomies, and deletions and/or duplications of segments of any one or more of the chromosomes, which can be detected by sequencing only once the nucleic acids of a test sample. Any aneuploidy can be determined from sequencing information that is obtained by sequencing only once the nucleic acids of a test sample.
    • 发明内容本发明提供了一种确定测试样品中感兴趣的序列的拷贝数变异(CNV)的方法,该方法包括已知或怀疑在一个或多个序列的量中不同的核酸的混合物 利益。 该方法包括统计方法,其考虑了由过程相关的染色体间和序列间变异性引起的应变变异性。 该方法适用于确定任何胎儿非整倍性的CNV,以及已知或怀疑与各种医学状况相关的CNV。 可以根据本方法确定的CNV包括染色体1-22,X和Y中的任何一个或多个的三体和单体,其他染色体多糖体,以及任何一个或多个染色体的区段的缺失和/或重复, 其可以通过仅测试一次测试样品的核酸来检测。 任何非整倍体都可以从通过测序一次核酸测试获得的测序信息来确定。
