  • Publication number: 20180173846
    Abstract: Provided herein are improved methods for detecting aneuploidy in a sample. The methods in certain embodiments are used for the analysis of circulating DNA in serum samples, such as circulating fetal DNA or circulating tumor DNA. In certain embodiments, chromosome or chromosome segments of interest are used to set a bias model and/or a control value for a z-score determination, in illustrative examples without the use of a control chromosome.

  • Publication number: 20180148777
    Abstract: The invention provides improved methods, compositions, and kits for detecting ploidy of chromosome regions, e.g. for detecting cancer or a chromosomal abnormality in a gestating fetus. The methods can utilize a set of more than 200 SNPs that are found within haploblocks and can include analyzing a series of target chromosomal regions related to cancer or a chromosomal abnormality in a gestating fetus. Finally the method may use knowledge about chromosome crossover locations or a best fit algorithm for the analysis. The compositions may comprise more than 200 primers located within haplotype blocks known to show CNV.

  • Publication number: 20170107576
    Abstract: The invention provides methods, systems, and computer readable medium for detecting ploidy of chromosome segments or entire chromosomes, for detecting single nucleotide variants and for detecting both ploidy of chromosome segments and single nucleotide variants. In some aspects, the invention provides methods, systems, and computer readable medium for detecting cancer or a chromosomal abnormality in a gestating fetus.

  • Publication number: 20160369333
    Abstract: The invention provides methods for simultaneously amplifying multiple nucleic acid regions of interest in one reaction volume as well as methods for selecting a library of primers for use in such amplification methods. The invention also provides library of primers with desirable characteristics, such as minimal formation of amplified primer dimers or other non-target amplicons.

  • Publication number: 20130261004
    Abstract: Methods for non-invasive prenatal paternity testing are disclosed herein. The method uses genetic measurements made on plasma taken from a pregnant mother, along with genetic measurements of the alleged father, and genetic measurements of the mother, to determine whether or not the alleged father is the biological father of the fetus. This is accomplished by way of an informatics based method that can compare the genetic fingerprint of the fetal DNA found in maternal plasma to the genetic fingerprint of the alleged father.

  • Patent number: 6578028
    Abstract: A graphical SQL query generator and query operators are disclosed. The query tool embeds matrix objects that are used for building and transforming SQL based queries, views, data cubes and other relations including “virtual” or calculated relations. The matrix objects trace the structure of a relation to its source data and thereby make the structure of complex multilayered database queries transparent to the end-user. The methods are especially useful in data warehousing where the buildup of fact tables in star or other schemas needs to be transparent to the user. Thus, a system is disclosed that is able to quickly reveal how data warehousing schemas and relations in SQL and similar relational type databases evolve from source data and each other into more complicated structures. It supports the creation and maintenance of complex database structures such as scientific studies and other decision support structures as well as simplifying ad-hoc querying of SQL databases.
