The primary purposes of the DECIPHER project are to:

  1. Increase medical and scientific knowledge about chromosomal microdeletions/duplications
  2. Improve medical care and genetic advice for individuals/families with submicroscopic chromosomal imbalance
  3. Facilitate research into the study of genes which affect human development and health

The Consortium anticipates that consented data generated from the project will be used by others, such as required for developing new analytical methods, in understanding patterns of polymorphism and in refining critical intervals to map genes involved in specific
phenotypes and diseases.
