Genomic structural variations (SVs) such as deletions, insertions, inversions, translocations and tandem duplications are an important class of genetic variations that underlies the genomic diversity in a population. Characterizing their underlying mechanisms and potential molecular consequences is crucial for understanding the basic biology of tumorigenesis. Here we engineered a local assembly based algorithm laSV that is able to detect structural variations (SV) with high accuracy from pair-end high-throughput genomic sequencing data and pinpoint their breakpoints at base-pair resolution. laSV can also estimate the allele frequencies of detected SVs, which will be useful for heterogeneous samples such as tumor samples.
