Donor DNA Databank

The Generation Scotland Donor DNA Databank (GS:3D) is a £170,209 project funded by the CSO Biomedical and Therapeutic Research Committee (see Timeline).

A centralised collection of control DNA samples

The purpose of the GS:3D project is to provide a large, well characterised collection of human control DNA samples accessible to researchers. This will lead to an improvement in the statistical power of many human genetics studies and avoid duplication of effort and expense.

Human genetic association studies can be hampered by the requirement to collect large numbers of appropriate control DNA samples. While case samples are necessarily unique to each disease study, the same control samples can be used across many studies if appropriately collected and characterised. The selection of control samples can influence the success of genetic association studies, but until now the choice of control samples from the Scottish population has been very limited. GS:3D provides access to a centralised collection of well maintained stocks of control DNA obtained with consent from the Scottish population.

Thousands of DNA and plasma samples from blood donors

The samples will be obtained from thousands of blood donors attending the Scottish National Blood Transfusion Service Donor Centres and mobile blood donation sessions across Scotland. Immediately before giving blood, potential participants will be provided with a leaflet describing the aims of GS:3D and an information sheet explaining what taking part involves. After being given time to ask questions, volunteers will then asked to fill in a consent form, answer a short questionnaire and allow part of their blood sample to be used for extraction of DNA and plasma for storage.
