  • Publication number: 20170058332
    Abstract: The present disclosure provides systems and methods to detect somatic or germline variants by providing a predetermined genomic DNA (gDNA) to an assay mixture, and capturing a sample of a subject's genetic information using a DNA sequencer and detecting genetic variants from the genetic information.

  • Patent number: 9574234
    Abstract: The present invention provides methods and compositions for analyzing nucleic acid sequences. In some aspects, the methods utilize clonal objects, such as DNA balls, that have been captured on beads. Using the methods described here, compositions are fabricated wherein a bead and one clonal object are affinity bound or hybridized to each other through an affinity binding patch or hybridization patch on the surface of the bead. The invention also provides a population of beads having affinity bound or hybridized clonal objects at a ratio of 1:1. The invention additionally provides methods for amplifying a target nucleic acid molecule utilizing the compositions described herein.

    Abstract: Polymer sequencing is facilitated. According to an example embodiment of the present invention, a polymer sequencing approach is implemented using a multitude of polymer specimens for a particular polymer type is implemented. For each step in a polymer sequencing test, non-idealities are categorized using data obtained from the polymer sequencing test, and in response to the categorized non-idealities, a polymer sequence is identified for a corresponding step of the polymer sequencing test. With this approach, read lengths achieved with a particular polymer sequencing method can be improved.
