  • Publication number: 20240060143
    Abstract: An analytics system marks duplicate fragments from an initial set of fragments from a subject. The analytics system generates a sample state vector for each fragment. Each sample state vector comprises a sample genomic location within a reference genome and a plurality of methylation states for a plurality of CpG sites in the fragment, the methylation states determined to be one of methylated, unmethylated, variant, and ambiguous. The analytics system identifies two fragments with methylation state vectors as being derived from a matching reference location, e.g., sharing a common plurality of CpG sites. The analytics system calculates a modified Hamming distance based on methylation states in the first sample state vector and methylation states in the second sample state vector. Based on the modified Hamming distance, the analytics system marks the first fragment and the second fragment as either duplicate fragments or non-duplicate fragments.

  • Publication number: 20210115520
    Abstract: Methods for screening for a cancer condition in a subject are provided. A biological sample from the subject is obtained. The sample comprises cell-free nucleic acid from the subject and potentially cell-free nucleic acid from a pathogen in a set of pathogens. The cell-free nucleic acid in the biological sample is sequenced to generate a plurality of sequence reads from the subject. A determination is made, for each respective pathogen in the set of pathogens, of a corresponding amount of the plurality of sequence reads that map to a sequence in a pathogen target reference for the respective pathogen, thereby obtaining a set of amounts of sequence reads, each respective amount of sequence reads in the set of amounts of sequence reads for a corresponding pathogen in the set of pathogens. The set of amounts of sequence reads is used to determine whether the subject has the cancer condition.
