  • Publication number: 20220068434
    Abstract: Techniques for cancer patient management, and more particularly, to techniques for ultrasensitive detection of circulating nucleic acid with prior knowledge of variants to be monitored in the blood. An exemplary technique includes detecting one or more variants in a sample of cell free DNA from a subject. The one or more variants are selected from a plurality of variants known to be specific to a tumor or disease area of the subject. The technique further includes counting the detected one or more variants, determining a tumor burden based on the count of the one or more variants, and determining a statistical significance of the tumor burden based on whether the detection of the one or more variants is associate with true signals or background noise.

  • Patent number: 10253349
    Abstract: Provided herein are methods and compositions for detecting gene fusions, e.g., relevant to cancer. The present methods and compositions can be used to detect gene fusions with very high sensitivity and specificity. The present methods and compositions can detect gene fusions, e.g., in free circulating tumor RNA from a plasma sample.

  • Patent number: 10127351
    Abstract: Accurate and fast mapping of sequencing reads obtained from a targeted sequencing procedure can be provided. Once a target region is selected, alternate regions of the genome that are sufficiently similar to the target region can be identified. If a sequencing read is more similar to the target region than to an alternate region, then the read can be determined as aligning to the target region. The reads aligning to the target region can then be analyzed to determine whether a mutation exists in the target region. Accordingly, a sequencing read can be compared to the target region and the corresponding alternate regions, and not to the entire genome, thereby providing computational efficiency.
