    摘要: The present invention provides a method capable of detecting single or multiple fetal chromosomal aneuploidies in a maternal sample comprising fetal and maternal nucleic acids, and verifying that the correct determination has been made. The method is applicable to determining copy number variations (CNV) of any sequence of interest in samples comprising mixtures of genomic nucleic acids derived from two different genomes, and which are known or are suspected to differ in the amount of one or more sequence of interest. The method is applicable at least to the practice of noninvasive prenatal diagnostics, and to the diagnosis and monitoring of conditions associated with a difference in sequence representation in healthy versus diseased individuals.

    摘要: 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.

    摘要: The invention provides methods for determining copy number of the Y chromosome, including, but not limited to, methods for gender determination or Y chromosome aneuploidy of fetus using maternal samples comprising maternal and fetal cell free DNA. Some embodiments disclosed herein describe a strategy for filtering out (or masking) non-discriminant sequence reads on chromosome Y using representative training set of female samples. In some embodiments, this filtering strategy is also applicable to filtering autosomes for evaluation of copy number variation of sequences on the autosomes. In some embodiments, methods are provided for determining copy number variation (CNV) of any fetal aneuploidy, and CNVs known or suspected to be associated with a variety of medical conditions. Also disclosed are systems for evaluation of CNV of sequences of interest on the Y chromosome and other chromosomes.

    摘要: Disclosed are methods and tools for rapidly aligning reads to a reference sequence. These methods and tools employ Bloom filters or similar set membership testers to perform the alignment. The reads may be short sequences of nucleic acids or other biological molecules and the reference sequences may be sequences of genomes, chromosomes, etc. The Bloom filters include a collection of hash functions, a bit array, and associated logic for applying reads to the filter. Each filter, and there may be multiple of these used in a particular application, is used to determine whether an applied read is present in a reference sequence. Each Bloom filter is associated with a single reference sequence such as the sequence of a particular chromosome. In one example, chromosomal abundance is determined by aligning reads from a sequencer to multiple chromosomes, each having an associated Bloom filter or other set membership tester.

    摘要: Methods of reliably estimating genomic fraction (e.g., fetal fraction) from polymorphisms such as small base variations or insertions-deletions are disclosed. Sequenced data from a multigenomic source is used to determine allele counts for one or more of the polymorphisms. For one or more of the polymorphisms, zygosity is assigned, and genomic fraction is determined from the zygosity and allele counts. Certain embodiments employ SNPs as the relevant polymorphism. The disclosed methods can be applied as part of an intentional, pre-designed re-sequencing study targeted against known polymorphisms or can be used in a retrospective analysis of variations found by coincidence in overlapping sequences generated from maternal plasma (or any other setting where a mixture of DNA from several people are present).
