  • Publication number: 20240096445
    Abstract: Illustrative embodiments of systems and methods for the identification of traits associated with DNA samples using epigenetic-based patterns detected via massively parallel sequencing (MPS) are disclosed. Illustrative embodiments may involve digesting a DNA sample with a methylation-dependent endonuclease, amplifying loci of the digested DNA sample (including a positive control locus that does not contain a restriction site for the methylation-dependent endonuclease) using a multiplex PCR to produce amplicons, sequencing the amplicons using an MPS instrument to generate sequence reads, determining a sequence count for each of the loci by comparing each of the sequence reads to reference sequences, normalizing the sequence count for each of the loci to the sequence count of the positive control locus, and identifying a trait associated with the DNA sample by applying a classification algorithm to the normalized sequence counts.

  • Publication number: 20230197196
    Abstract: In one illustrative embodiment, an allelotyping method may include selecting a plurality of text strings that each represent a nucleotide sequence that was read by a massively parallel sequencing (MPS) instrument, where the nucleotide sequences represented by the selected plurality of text strings each correspond to a particular locus, comparing the selected plurality of text strings to one another to determine an abundance count for each unique text string included in the selected plurality of text strings, and determining one or more alleles for the particular locus by comparing the abundance count for each unique text string included in the selected plurality of text strings to an abundance threshold.

  • Patent number: 11475980
    Abstract: In at least one illustrative embodiment, a method may comprise selecting a first plurality of text strings that each represent a nucleotide sequence that was read by a massively parallel sequencing instrument, where the nucleotide sequences represented by the selected first plurality of text strings each correspond to a first target locus, comparing the selected first plurality of text strings to one another to determine an abundance count for each unique text string included in the selected first plurality of text strings, identifying a first number of unique text strings included in the selected first plurality of text strings as representing noise responses, and determining a method detection limit as a function of the abundance counts for the first number of unique text strings identified as representing noise responses.

  • Publication number: 20200135297
    Abstract: In one illustrative embodiment, an allelotyping method may comprise using a massively parallel sequencing (MPS) instrument to read nucleotide sequences in a sample and to generate nucleotide sequence data quantifying each read of a nucleotide sequence in the sample, determining, for each read by the MPS instrument, whether a portion of the generated nucleotide sequence data represents a short tandem repeat (STR) associated with a corresponding locus, adding each portion of the nucleotide sequence data determined to represent an STR to a locus-specific list for the corresponding locus, determining, for each locus-specific list, a number of occurrences within that locus-specific list of identical nucleotide sequence data representing a unique STR, and identifying each unique STR for which the number of occurrences of identical nucleotide sequence data within the locus-specific list exceeds an abundance threshold as an allele of the corresponding locus for the sample.
