Abstract: The invention relates to carrier screening and methods for describing a structural variant, such as a large rearrangement or chromosomal abnormality, in a person's genome using probes that are designed to determine the person's genetic sequence and reveal substitution mutations and small structural variants. Identifying a structural variant may include exposing a nucleic acid to a plurality of probes. Each probe has a linked pair of targeting arms designed to hybridize upstream and downstream of a target in a genome. The method includes hybridizing two of the probes to the nucleic acid and attaching the two probes together to create an inter-probe product as well as detecting the inter-probe product and reporting a structural variant of the genome in the nucleic acid.

Abstract: The present disclosure relates to methods for constructing polynucleotide libraries and/or polynucleotide sequencing. Related kits and devices are also disclosed. The present disclosure also relates to compositions, kits, devices, and methods for conducting genetic and genomic analysis, for example, by polynucleotide sequencing. In particular aspects, provided herein are compositions, kits, and methods for constructing libraries with improved ligation efficiency and conversion rate during sequencing. In certain embodiments, the compositions, kits, and methods herein are useful for analyzing polynucleotide fragments, such as circulating polynucleotide fragments in the body of a subject, including circulating tumor DNA.

Abstract: The invention generally relates to negative selection of nucleic acids. The invention provides methods and systems that remove unwanted segments of nucleic acid in a sample so that a target gene or region of interest may be analyzed without interference from the unwanted segments. A sample is obtained that includes single-stranded nucleic acid with one or more unwanted segments. Complementary nucleic acid is added to the single-stranded nucleic acid to create a double-stranded region that includes the unwanted segment. The double-stranded region is then digested, leaving single-stranded nucleic acid that includes the target gene or region of interest. This allows paralogs, pseudogenes, repetitive elements, and other segments of the genome that may be similar to the target gene or region of interest to be removed from the sample.

Abstract: The invention generally relates to methods for determining aneuploidy of cells with respect to a control sample. In certain embodiments, the method involves exposing a sample to a plurality of probes capable of capturing DNA from at least one chromosome suspected of having an altered copy number, and at least one control DNA sample known or suspected to have a stable copy number, capturing and sequencing DNA that binds to the probes, calculating a chromosomal read fraction; determining a sample specific scaling factor; scaling the chromosomal read fractions, normalizing the scaled read fractions, and determining a copy number state of at least one chromosome.

Abstract: The present invention provides methods for validating results of a pre-implantation genetic screen. Methods of the invention increase the efficacy of the common PGS assay FAST-SeqS by taking advantage of single-nucleotide polymorphisms (SNPs) generated from the assay to confirm copy number calls, detect errors, identify samples, and recognize and identify sources of contamination. Methods of the invention increase the reliability of a PGS result, thereby making embryo selection more precise and improving outcomes of in vitro fertilization.

Abstract: The invention generally relates to devices and systems for individually barcoding sample vessels. In certain embodiments, the devices comprise an attachment member and an extension member, where the extension member can accommodate an identifier, such as a barcode. When loaded into a substrate, the barcoded vials are scanned by a barcode reader.

Abstract: Methods for improving variant protection are provided. The methods include the steps of generating an in silico genome map that includes a primary path, and a secondary path comprising variants that were missed or incorrectly called in a sequence assembly simulation, aligning the secondary path to the primary path, convoluting the second path to the primary path, and identifying the variants based upon reads that align with the secondary path but not the primary path. All of method steps can be carried out using a computer. Systems incorporated these methods are also included.
