Abstract

An analysis technique for enriching one or more target regions in molecules of deoxyribonucleic acid (DNA) in a sample (such as a tissue sample or cell-free DNA) is described. Notably, in this analysis technique, adapters are attached to ends of the molecules of DNA. Then, the molecules of DNA are selectively cut in one or more off-target regions in the molecules of DNA. The selective cutting may use a Cas9 protein or a restriction enzyme. Moreover, the one or more off-target regions in the molecules of DNA are depleted or removed, where the off-target regions are different from the target regions. Next, after the depleting or removing operation, motor adapters are attached to a remainder of the molecules of DNA. In some embodiments, the one or more target regions are analyzed by pulling or extracting the remainder of the molecules of DNA through an analysis membrane using the motor adapters.

Abstract

Disclosed herein in are methods and systems for determining genetic variants (e.g., copy number variation) in a polynucleotide sample. A method for determining copy number variations includes tagging double-stranded polynucleotides with duplex tags, sequencing polynucleotides from the sample and estimating total number of polynucleotides mapping to selected genetic loci. The estimate of total number of polynucleotides can involve estimating the number of double-stranded polynucleotides in the original sample for which no sequence reads are generated. This number can be generated using the number of polynucleotides for which reads for both complementary strands are detected and reads for which only one of the two complementary strands is detected.

Abstract

A disease classification method includes determining, using a predictive model, whether cell-free nucleic acid samples are tumor-derived or non-tumor derived based on at least one of the cell-free nucleic acid score or a tumor fraction regression (TFR) score satisfying a respective threshold. The TFR score is determined based on a quantification of an observed tumor-associated aberrant methylation of each of a plurality of cell-free nucleic acid samples using a TFR model. The TFR score includes a fraction of molecules of the plurality of cell-free nucleic acid samples that indicate a tumor. The cell-free nucleic acid score is indicative of the presence of a tumor, and is based on at least one of epigenetic factors or genomic alterations of the cell-free nucleic acid samples.

Abstract

Disclosed herein are methods for isolating DNA, such as cell-free DNA (cfDNA) or DNA from a tissue sample, e.g., in which the DNA is partitioned into hypermethylated and hypomethylated partitions. After differential tagging of the partitions, portions of the hypomethylated partition are pooled with the hypermethylated partition or pooled separately. Epigenetic and sequence-variable target regions are captured from the pool comprising DNA from the hypermethylated and hypomethylated partitions, and sequence-variable target regions are captured from the pool comprising DNA from the hypomethylated partition. This approach can reduce costs and/or bandwidth by limiting sequencing of epigenetic target regions from the hypomethylated partition, which may be less informative than other DNA.

Abstract

The disclosure relates to improved sequencing reactions. Specifically, the disclosure provides methods which allow for the identification of regions of a DNA molecule that were synthesized during an end repair and/or A-tailing reaction. Sequence data deriving from such synthesized regions may not be representative of the corresponding region in the original DNA molecules, for example it may contain artifactual methylation statuses. Accordingly, the identification of these synthesized regions allows for such potentially artifactual data to be identified and filtered accordingly.

Abstract

Disclosed herein in are methods and systems for determining genetic variants (e.g., copy number variation) in a polynucleotide sample. A method for determining copy number variations includes tagging double-stranded polynucleotides with duplex tags, sequencing polynucleotides from the sample and estimating total number of polynucleotides mapping to selected genetic loci. The estimate of total number of polynucleotides can involve estimating the number of double-stranded polynucleotides in the original sample for which no sequence reads are generated. This number can be generated using the number of polynucleotides for which reads for both complementary strands are detected and reads for which only one of the two complementary strands is detected.

Abstract

The disclosure relates to improved sequencing reactions. Specifically, the disclosure provides methods which allow for the identification of regions of a DNA molecule that were synthesized during an end repair and/or A-tailing reaction. Sequence data deriving from such synthesized regions may not be representative of the corresponding region in the original DNA molecules, for example it may contain artifactual methylation statuses. Accordingly, the identification of these synthesized regions allows for such potentially artifactual data to be identified and filtered accordingly.

Abstract

The present application provides methods of sequencing populations of nucleic acids within multiple pooled samples with tracking of individual molecules and their samples of origin. In such methods, the same sequencing read provides in line sequences of sample and molecular barcodes and a sample molecule allowing deconvolution of sequencing reads to sample of origin and grouping of amplification copies of original molecules into families. The methods are amenable to multiple sequencing platforms, reduce uninformative portions of sequencing reads on adapter sequence common to all adapters, decrease opportunity for labelling samples with the wrong barcode (index hopping), and provide additional multiplexing capacity.

Abstract

DNA damage (e.g., cytosine deamination) can appear more frequently in hypermethylated partitions of DNA (e.g., cell-free DNA) samples, than in hypomethylated partitions. Embodiments include sequencing hypermethylated partitions and hypomethylated partitions wherein calling a C to T or G to A transition mutation relative to a reference sequence based on sequences of molecules from the hypermethylated partition requires observation of the transition mutation in a greater number of molecules than calling a C to T or G to A transition mutation relative to the reference sequence based on sequences of molecules from the hypomethylated partition, or C to T or G to A transition mutations are not called relative to a reference sequence based on sequences of molecules of the hypermethylated partition.

Abstract

Disclosed herein in are methods and systems for determining genetic variants (e.g., copy number variation) in a polynucleotide sample. A method for determining copy number variations includes tagging double-stranded polynucleotides with duplex tags, sequencing polynucleotides from the sample and estimating total number of polynucleotides mapping to selected genetic loci. The estimate of total number of polynucleotides can involve estimating the number of double-stranded polynucleotides in the original sample for which no sequence reads are generated. This number can be generated using the number of polynucleotides for which reads for both complementary strands are detected and reads for which only one of the two complementary strands is detected.

Abstract

The invention provides methods of generating forward and reverse reads of an immobilized single-stranded target nucleic acid using multifunctional primers. A multifunctional primer serves to initiate separate syntheses of first and second complementary strands to the single-stranded target nucleic acid, and to tether the first complementary strand to the immobilized target nucleic acid. The first complementary strand serves to provide a primer binding site and template for an extension product to generate a reverse sequencing read. The second complementary strand serves to displace the first complementary strand from duplexing with the target nucleic acid. The first or second complementary strand can provide a forward sequence read.
