Generation Scotland: Donor DNA Databank; A control DNA resource

Area of Science:

• Genetics
• Public Health
• Biobanking

Background:

• Complex diseases arise from genetic, environmental, and lifestyle factors.
• Genome-wide association studies (GWAS) require large case and control cohorts.
• Acquiring suitable control samples for GWAS is a significant challenge.

Purpose of the Study:

• To establish the Generation Scotland: Donor DNA Databank (GS:3D) as a research resource.
• To provide accessible control DNA and plasma samples for genetic research.
• To overcome difficulties in recruiting control participants for large-scale studies.

Main Methods:

• Recruitment of participants from volunteer blood donors at Scottish National Blood Transfusion Service clinics.
• Collection of spare blood samples with full written consent.
• Gathering of demographic data via questionnaires.

Main Results:

• Over 5,000 complete sets of DNA, plasma, and demographic data were collected.
• Samples and data were de-identified and stored for research access.
• The resource includes DNA, plasma, and demographic information.

Conclusions:

• Recruiting blood donors is an efficient and cost-effective method for large-scale control sample collection.
• The GS:3D resource enables selection of control subsets based on demographics.
• GS:3D reduces the time and cost for researchers needing control samples.
