This graph shows the increase in published structural variation data that have been added to the database since its start in 2004; the numbers reflect the year of publication.
Size distribution (CNV)
The graph displays the size distribution of CNVs in the database.
Number of Studies
This graph shows the number of studies currently in DGV by published year.
The table shows the data underlying the graph showing the non-redundant CNV coverage per chromosome. Note that there are several biases going into the underlying data. Specifically, studies based on BAC arrays tend to significantly overestimate the size of variants. At the same time, there are still a lot of smaller CNVs (<30kb) that remain to be identified.
The following table shows the overlaps of CNVs with relevant genomic features. It is important to remember that many CNVs currently have overestimated boundaries, which leads to an exaggeration of the number of features overlapping CNVs. The genes refer to NCBI RefSeq genes and the OMIM category includes genes that are represented in the OMIM Morbid Map.
