Abstract: A method is described for determining carrier status of an embryo for a balanced chromosomal rearrangement (BCR) prior to implantation of the embryo. The method involves obtaining cells from the embryo from at least day 4 post in vitro fertilization; conducting long-read nanopore sequencing of the DNA of the cells and the BCR carrier parent to detect at least one breakpoint; preparing primers specific to the breakpoint; employing the primers in a polymerase chain reaction customized to the breakpoint (cBP-PCR) to determine whether the breakpoint is indicative of BCR; and determining on the basis of cBP-PCR whether the embryo status is BCR carrier or BCR noncarrier; and conducting Sanger sequencing to determine balance in the embryo. The method can assist BCR carrier parents to pursue reproductive technologies while preventing vertical transmission of a BCR to offspring.

Abstract: The identification of mutations that are present in a small fraction of DNA templates is essential for progress in several areas of biomedical research. Though massively parallel sequencing instruments are in principle well-suited to this task, the error rates in such instruments are generally too high to allow confident identification of rare variants. We here describe an approach that can substantially increase the sensitivity of massively parallel sequencing instruments for this purpose. One example of this approach, called “Safe-SeqS” for (Safe-Sequencing System) includes (i) assignment of a unique identifier (UID) to each template molecule; (ii) amplification of each uniquely tagged template molecule to create UID-families; and (iii) redundant sequencing of the amplification products. PCR fragments with the same UID are truly mutant (“super-mutants”) if ?95% of them contain the identical mutation.
