Platform | General characteristic | Key features for the determination of SVs | Limitations for the determination of SVs |
---|---|---|---|
Long reads sequencing (Oxford Nanopore Sequencing, PacBio SMRT sequencing) | Single-molecule long read sequencing averaging ∼10 k | Single reads spanning whole SV or its break points | Large quantities of high molecular weight DNA High error rate |
BioNano Genomics optical mapping | Optical mapping of long DNA reads ∼250 kb or longer | Single molecule spanning structural variants > 10 kb | Does not provide a nucleotide-level resolution of breakpoints |
10X Genomic Chromium | Linked short reads spanning ∼100 kb | Linked reads spanning ∼100 kb can detect large SV variants > 10 kb | Unable to identify complex inversions |
Hi-C based analysis | Pairs of short reads formed from crosslinking chromatin interactions | Chromatin contact maps determining large SV with reads spanning breakpoints and reads located nearby the breakpoints | Limited in detecting SVs within 1 MB scale Does not provide a nucleotide-level resolution of breakpoints |
Strand-Seq | Single-cell/single-strand genome sequencing | Possible to identify, haplotypes and h genomic rearrangements including complex inversions | High cost and demanding procedure (the protocol requires viable mitotic cells) |
