Abstract: Technology provided herein relates in part to methods, processes, machines and apparatuses for non-invasive assessment of genetic alterations. In particular, a method is provided for that includes obtaining nucleic acid fragments from a sample from a test subject; sequencing the sequence constructs to obtain sequence reads; demultiplexing the sequence reads to a first and a second subset of sequences reads; generating a first set of consensus reads that correspond to the first nucleic acid fragment based on SMBs associated with the first subset of sequences reads; generating a second set of consensus reads that correspond to the second nucleic acid fragment based on SMBs associated with the second subset of sequences reads; and determining a presence of one or more genetic alterations for the test subject based on the two sets of consensus reads.

Abstract: Array-based targeted copy number detection, for instance detection on contaminated and/or variable concentration samples, includes obtaining a collection of intensity signals from assays of a set of input samples, performing a cross-sample calibration on the intensity signals based on reference sample(s), which calibration includes constructing a reference signal distribution based on intensity signals of the reference sample(s) and for one or more input samples calibrating a set of intensity signals corresponding to the input sample based on the reference signal distribution, determining, for the one or more input samples, and from a respective one or more calibrated sets of intensity signals corresponding to the one or more input samples, a respective at least one aggregated calibrated signal from targeted genomic region(s) to produce a collection of aggregated calibrated signals, and detecting variant(s) in the targeted genomic region(s) based on the collection of aggregated calibrated signals.

Abstract: Technology provided herein relates in part to methods, processes, machines and apparatuses for non-invasive assessment of genetic alterations. In particular, a method is provided for that includes obtaining a set of sequence reads. The sequence reads each include a single molecule barcode (SMB) sequence that is a non-random oligonucleotide sequence. The method further includes assigning the sequence reads to read groups according to a read group signature. The read group signature comprises an SMB sequence and a start and end position of a nucleic acid fragment from the circulating cell free sample nucleic acid. The sequence reads comprising start and end positions and an SMB sequence similar to the read group signature are assigned to a read group. The method further includes generating a consensus for each read group, and determining the presence or absence of a genetic alteration based on the consensus for each read group.
