  • Publication number: 20220215901
    Abstract: The present disclosure describes a sequencing system configured to identify structural variants in mitochondrial DNA. Variant callers configured to identify variants in linear genomes (e.g., those found in chromosomes) can fail to properly identify structural variants in mitochondrial DNA. The system and methods can identify structural variants in next generation sequencing data collected from circular, mitochondrial DNA.

  • Publication number: 20220042110
    Abstract: Described herein are methods and kits for detecting the presence or absence of gene dysregulations such as those arising from gene fusions and/or chromosomal abnormalities, e.g. translocations, insertions, inversions and deletions. The methods, compositions and kits are useful for detecting mutations that cause the differential expression of a 5? portion of a target gene relative to the 3? region of the target gene. The average expression of the 5? portion of the target gene is compared with the average expression of the 3? portion of the target gene to determine an intragenic differential expression (IDE). The IDE can then be used to determine if a dysregulation or a particular disease (or susceptibility to a disease) is present or absent in a subject or sample.

  • Publication number: 20210363569
    Abstract: The present invention relates to methods for the diagnosis of bacterial vaginosis based on an analysis of a patient sample. For example, patient test samples are analyzed for the presence or absence of one or more lactobacilli and two or more pathogenic organisms. The presence or absence of one or more lactobacilli and two or more pathogenic organisms may be detected using PCR analysis of nucleic acid segments corresponding to each target organism. The quantity of the target organisms can then be used to determine a score which is indicative of a diagnosis of bacterial vaginosis.
