Abstract: Contemplated systems and methods employ chimeric reference sequences that include a plurality of viral genome sequences to identify/quantify integration and co-amplification events. Most typically, the viral genome sequences are organized in the chimeric reference sequences as single chromosomes and the chimeric reference sequences are in BAM format.

Abstract: Methods for rapidly and accurately detecting genetic material from hop latent viroid RNA (HLVd) that combines reverse transcription loop-mediated isothermal amplification (RT-LAMP) technology with specific oligonucleotide primers, fluorophore-labeled oligonucleotide primers, quencher-conjugated oligonucleotide primers, pH buffers, and enzymes, are described. The methods include at least one internal positive control targeting sequence, for minimizing false positive and false negative results, thereby allowing more certain interpretation of the results. The reaction can be performed at a single elevated temperature, can be completed in 1-1.5 hours, and the results can readily be interpreted by visually observing the fluorescence color of the reaction using ultraviolet light, or by using an electronic image acquisition system for viewing fluorescence results from one or more reactions.

Abstract: The disclosure relates to methods, compositions, and kits for the early determination of the sex of a fetus. The disclosure also provides methods, compositions, and kits for detecting fetal nucleic acids in biological samples (e.g., cell-free fetal DNA). An embodiment includes a method of improving the accuracy of fetal sex determination by reducing a level of contaminating DNA in a blood sample from a pregnant human subject, comprising obtaining a capillary blood sample collected from the upper arm using a push-button blood collection device, thereby reducing a level of contaminating DNA from a non-maternal and non-fetal source in the capillary blood sample as compared to a blood sample collected from a site on the finger or hand of the subject, and detecting the presence or absence of fetal Y-chromosome to determine the sex of the fetus.

Abstract: Disclosed herein are compositions, systems, kits and methods related to preserving physical linkage information of isolated DNA subject to DNA damage, and identifying a nucleic acid preservative. Physical linkage information and DNA integrity may be preserved by methods relating to reassembly of chromatin onto isolated DNA molecules so as to protect the nucleic acids, preserve physical linkage information, or size select molecules of interest. Nucleic acid compositions produced by methods disclosed herein are preserved so as to be analyzed, for example, by high throughput sequencing methods.

Abstract: Disclosed herein are compositions, systems and methods related to sequence assembly, such as nucleic acid sequence assembly of single reads and contigs into larger contigs and scaffolds through the use of read pair sequence information, such as read pair information indicative of nucleic acid sequence phase or physical linkage.

Abstract: A sampling device having a lower portion with a sample container. A cap is moveably attached with the lower portion and includes a cutting edge configured for cutting a leaf. When the cap is attached to the lower portion with a leaf there between, a leaf sample is deposited into the sample container of the lower portion. The cap includes a vent in fluid communication with the sample container such that the leaf sample is dried. A detachable label can extend from the lower portion.

Abstract: Systems and methods of genomic analysis are presented that provide a framework to determine a tumor's clonality, the number and proportion of all major clones, and the variants that distinguish them. Contemplated systems and methods also allow phasing mutations to parental alleles to so time their emergence within the population of tumor cells, and provide an accurate estimate of the amount of contaminating normal tissue that was present in the tumor biopsy.

Abstract: The disclosure pertains to materials and methods for capturing a target genomic region, comprising hybridizing an extension probe and a ligation probe to target sequences that flank the target genomic region; elongating the 3? end of the extension probe until the 3? end of the elongated extension probe is adjacent to the 5? end of the ligation probe; and ligating the 3? end of the elongated extension probe with the 5? end of the ligation probe to produce a ligated probe. The ligated probe can be PCR amplified to produce copies of the target genomic region that can be detected or sequenced. Certain embodiments of the invention also provide methods of producing double stranded probes suitable for capturing and analyzing both strands of a target genomic region in a double stranded genomic DNA. The invention also provides kits for performing the methods disclosed herein.

Abstract: Contemplated systems and methods allow for computational genomic analysis using paired-end sequence analysis and split read refinement to thereby identify high-confidence breakpoints associated with high copy numbers and orientation of rearrangements, which is then the basis for full reconstruction of double minutes (DM). In especially preferred aspects, the DM will also include an oncogene or tumor suppressor gene, and/or may be found in blood or blood derived fluids.

Abstract: Cancer types (e.g., organ/tissue of origin and/or cancer subtype for an organ/tissue) can be distinguished by applying statistical methods to data samples consisting of counts of somatic single nucleotide variations (SNVs) across a tumor genome of a patient. For example, a factor loading matrix for each cancer type to be distinguished can be computed using a set of training data samples for which the cancer type is known. To determine the cancer type for a testing (or diagnostic) data sample, a regression analysis over the set of factor loading matrices yields statistical parameters that can be used to identify the cancer type.
