If NIPT is offered for a specific set of conditions (eg trisomies 21, 18 and 13), it may not be reasonably possible to avoid additional findings, such as other chromosomal anomalies or large scale insertions or deletions.
We therefore tested two previously established methods for large-scale insertion site determination, thermal asymmetric interlaced (TAIL -PCR [ 40, 41] and splinkereTAIL -PCRor PCR [ 40, 41].
The basis for this observation is well understood; MLST-based phylogeny reflects relatively slow genome evolution caused by point mutations and selective pressure, whereas the gene content dendrogram captures more rapid (and unpredictable) large-scale insertion and deletion events.
We have predicted 4314 GRs including large-scale insertions, deletions, inversions and translocations based on the whole-genome sequencing data for 88 primary HCC tumor/non-tumor tissues.
Large-scale insertions were determined by identifying reads not mapping into the F11 genome that significantly cover regions in other mycobacterial genomes.
In GenomeRing, however, we do not only want to visualize rearrangements but also large-scale insertions and deletions.
Large-scale insertions were determined by building contigs that spanned fragments, neither of whose paired ends mapped into the H37Rv genome.
Gradual change seems to be a superior factor for the evolution of gene content of Listeriae when compared to large-scale insertions of multiple genes by mobile elements.
Genomic structural variants are comprised mainly of copy number variations (CNVs) in the form of large-scale insertions and deletions, as well as inversions and translocations [ 17].
Although highly accurate for the detection of single-nucleotide variants and small insertions or deletions, this approach is expensive, labor intensive and unable to detect large-scale insertions or deletions.
Thus, large-scale insertions, which resulted mainly from bacteriophage integration, run contrary to the "true" phylogenetic signal by inserting many genes in one event as well as by putative parallel insertions into different strains.
