Patent number: 10883139Abstract: Disclosed herein in are methods and systems for determining genetic variants (e.g., copy number variation) in a polynucleotide sample. A method for determining copy number variations includes tagging double-stranded polynucleotides with duplex tags, sequencing polynucleotides from the sample and estimating total number of polynucleotides mapping to selected genetic loci. The estimate of total number of polynucleotides can involve estimating the number of double-stranded polynucleotides in the original sample for which no sequence reads are generated. This number can be generated using the number of polynucleotides for which reads for both complementary strands are detected and reads for which only one of the two complementary strands is detected.Type: GrantFiled: February 8, 2018Date of Patent: January 5, 2021Assignee: GUARDANT HEALTH, INC.Inventors: Helmy Eltoukhy, AmirAli Talasaz, Stefanie Ann Ward Mortimer
