The Database of Genomic Structural Variation (dbVar) is a National Center for Biotechnology Information (NCBI) archival database that manages sequence variation. dbVar complements dbSNP by archiving copy number variants (CNV), insertions, deletions, inversions, and translocations (1) that are longer than 50 base pairs (bp). The database is organized around the studies that have identified these variants, and includes variations from research-based and clinical submissions. Structural variants that have asserted germline or somatic clinical significance should be submitted to Clinvar which will forward appropriate portions of the data to dbVar for accessioning.
