The nanochannel-based Genome Mapping technology, commercialized as the Irys Platform, automatically images fluorescently labeled DNA molecules in a massively parallel nanochannel array. This technology has previously been used to map the 4.7-Mb highly variable human MHC region, as well as for de novo assembly of a 2.1-Mb region in the highly complex Aegilops tauschii genome, lending great promise for use in complete genome sequence analysis.
Here, we apply this rapid and high-throughput genome mapping method to discern genome wide structural variations (SVs) as well as explore complex regions based on the YH (first Asian genome) cell line.
A structural variant (SV) is generally defined as a region of DNA 1 kb and larger in size that is changed with respect to another sample; examples include inversions, translocations, deletions, duplications and insertions. Deletions and duplications are also referred to as copy number variants (CNVs). Structural variants (SVs) are less common than single nucleotide polymorphisms (SNPs) or insertions/deletions (InDels) in the population but collectively account for a significant fraction of genetic polymorphism and diseases.
Utilizing Genome Mapping, we identified 725 SVs including InDels, inversions as well as SVs involved in N-base gap regions that are difficult to assess by current methods. The data presented here are the processed .tiff image files together with the interpreted .metrics file for each restriction map.
