Abstract

Comparisons of human genomes show that more base pairs are altered as a result of structural variation - including copy number variation - than as a result of point mutations. Here we review advances and challenges in the discovery and genotyping of structural variation. The recent application of massively parallel sequencing methods has complemented microarray-based methods and has led to an exponential increase in the discovery of smaller structural-variation events. Some global discovery biases remain, but the integration of experimental and computational approaches is proving fruitful for accurate characterization of the copy, content and structure of variable regions. We argue that the long-term goal should be routine, cost-effective and high quality de novo assembly of human genomes to comprehensively assess all classes of structural variation.

  • Determination of the length, weight and relative GC content of genome is subjected to the accuracy of the genome assembly and to the variability existing among individuals.

    “Determination of the length, weight and relative GC content of genome is subjected to the accuracy of the genome assembly and to the variability existing among individuals [41].”

    From On the length, weight and GC content of the human genome (2019) · cites this paper as [41]

    The Sequence assembly section (page unavailable) says accurate characterization of structural variation depends on sufficiently accurate reads and high-quality assembly. The Array CGH section (page unavailable) describes variation among individuals and difficulty accurately assessing the proportion of the genome altered. Neither passage supports the claim about determining genome weight or relative GC content. (LLM, conf=0.85)

  • Human genetic diversity ranges from single-nucleotide variation to large chromosomal events.

    “However, the human genetic diversity ranges from the single-nucleotide variation to large chromosomal events [41, 42].”

    From On the length, weight and GC content of the human genome (2019) · cites this paper as [41]

  • Current genotyping platforms and CNV discovery algorithms can genotype about 1,000 common copy-number polymorphisms and discover additional novel CNVs, including rare or individual-specific mutations.

    “Current genotyping platforms and CNV discovery algorithms enable the genotyping of ~1000 common copy number polymorphisms (CNPs) and the discovery of additional “novel” CNVs, including mutations that are rare or unique to an individual (Alkan et al., 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
