In some aspects, the present disclosure provides methods for identifying sequence variants, as well as methods of determining copy number of a genetic locus in a sample. Systems and kits for performing methods of the disclosure, as well as compositions produced by or useful in methods of the disclosure are also provided. In some embodiments, methods comprise extending 3' ends of polynucleotides by adding one or more pre-determined nucleotides. In some embodiments, methods comprise use of a strand-tagging sequence.

Method of improved sequencing by strand identification

In some aspects, the present disclosure provides methods for identifying sequence variants in a nucleic acid sample. In some embodiments, a method comprises identifying sequence differences between sequencing reads and a reference sequence, and calling a sequence difference that occurs in at least two different circular polynucleotides, such as two circular polynucleotides having different junctions, as the sequence variant. In some aspects, the present disclosure provides compositions and systems useful in the described methods.

Compositions and methods for detecting rare sequence variants

In some aspects, the present disclosure provides methods for identifying sequence variants in a nucleic acid sample. In some embodiments, a method comprises identifying sequence differences between sequencing reads and a reference sequence, and calling a sequence difference that occurs in at least two different circular polynucleotides, such as two circular polynucleotides having different junctions, or two different sheared polynucleotides as the sequence variant. In some aspects, the present disclosure provides compositions and systems useful in the described method.
