New and Updated Online Tutorials for dbGaP, GAD, and DGV from OpenHelix

Comprehensive tutorials on the publicly available dbGaP, GAD, and DGV databases enable researchers to quickly and effectively use these invaluable resources.

Seattle, WA (PRWEB) July 16, 2009 -- OpenHelix today announced the availability of new tutorial suites on dbGaP, Genetic Assocation Database (GAD) and Database of Genomic Variants (DGV). The dbGaP resource is a database of genotypes and phenotypes with extensive variation data and clinical details GAD is an annotated resource connecting human genes and polymorphisms to diseases and traits, and DGV or Database of Genomic Variants, catalogs and displays structural variation in the human genome. These three new tutorials in conjunction with additional OpenHelix tutorials on dbSNP, VISTA, HapMap, GeneSNPs, SeattleSNPs, Genome Variation Server and many others, give the researcher an excellent set of training resources to assist in their genetic association and variation research.

The tutorial suites, available for single purchase or through a low- priced yearly subscription to all OpenHelix tutorials, contain an online, narrated, multi-media tutorial, which runs in just about any browser connected to the web, along with slides with full script, handouts and exercises. These tutorials will teach users:


  • to perform basic and advanced searches and navigate the dbGaP site
  • to understand the displays for the main open access data types: studies, variables, documents, and analyses
  • to use the analysis browser to identify candidate genomic regions for genotype-phenotype associations and to manipulate and customize the browser displays GAD

  • to view GAD tables from different perspectives
  • to read detailed reports for unique genetic associations
  • to perform basic searches for genes, diseases, polymorphisms, environmental factors, and references
  • to perform advanced queries
  • to do a batch query for a large gene list
  • add a new genetic association or edit an existing one

  • to browse and search through DGV's structural variant data
  • how to find, understand and link to more genomic variation details
  • to navigate and customize your data using the genome browser
  • how to perform a BLAT sequence search

With the tutorials, researchers can quickly learn to effectively and efficiently use these resources. The scripts, handouts and other materials can also be used as a reference or for training others. To find out more about these and over 70 other tutorial suites visit the OpenHelix Catalog and OpenHelix. Or visit the OpenHelix Blog for up-to-date information on genomics and genomics resources.
