WebJun 15, 2015 · To describe a structural variant, we need more than just two positions, one per breakend. The breakends aren’t just points; they can be thought of as half-intervals, (eg, the piece of Chromosome 1 leading up to position 500; or the piece of Chromsome 1 starting at and continuing from position 500), and we will need that directional information.
