Introduction to NCBI Bioinformatics Resources: dbVar

A concise introduction to the various bioinformatic data available from NCBI.

dbVAR

dbVar

dbVar is NCBI's database of genomic structural variation – it contains insertions, deletions, duplications, inversions, multinucleotide substitutions, mobile element insertions, translocations, and complex chromosomal rearrangements. (from the NCBI web site)

NCBI provides an FAQ on dbVAR at http://www.ncbi.nlm.nih.gov/dbvar/content/help/

This guide will show a sample variation viewer using the LCT gene as the source.

First change the database search to dbVar and create a search for the gene we are interested in and limit to the organism:

 

The resulting page shows larger scale variations for this this gene.   Choosing one, nsv1123397, click on the link to view this variation in more detail:
