High-Resolution DNA Sequencing Data for 37,000 Children and Parents over Decades Across the UK Now Available to Researchers Worldwide.

A unique resource to explore the relationship between genetic and environmental factors in child health and development.

In a groundbreaking development, high-resolution DNA sequencing data for over 37,000 children and parents, collected over multiple decades from across the UK, has been released and is now available to researchers worldwide. This monumental release marks a significant milestone in the field of genomics and offers an unprecedented opportunity for scientific exploration and discovery.

The Data Release

The data release is led by the Wellcome Sanger Institute, in collaboration with the Children of the 90s study (also known as ALSPAC), the Millennium Cohort Study (MCS), and Born in Bradford (BiB). Supported by the Medical Research Council (MRC) and the Economic and Social Research Council (ESRC), this initiative is part of the ongoing efforts of Population Research UK, a UK-wide initiative led by teams at the University of Bristol and University College London.

What the Data Includes

The released data includes high-resolution DNA sequencing of all 20,000 genes in the human genome, known as exome sequencing. The samples were collected from 8,436 children and 3,215 parents from the Children of the 90s study, 7,667 children and 6,925 parents from the MCS, and 8,784 children and 2,875 parents from BiB. This comprehensive dataset is now available on the European Genome-phenome Archive (EGA), providing researchers with access to high-quality genomic data combined with existing longitudinal health and survey information provided by participating families.

The Significance of the Data

This data release is particularly significant because it focuses on sequencing "birth cohorts," which are population-based cohorts of people followed from birth through to adolescence or early adulthood. Previously, large DNA sequence datasets have typically focused on children with rare conditions or adult population cohorts. By including birth cohorts, this dataset offers a unique resource to explore the relationship between genetic and environmental factors in child health and development.

Potential Applications

The combined data resources offer the scientific community the opportunity to make valuable insights in areas ranging from population genetics to the social sciences. For example, researchers can investigate the impact of genetic variation on neurodevelopmental conditions or childhood obesity and how these are influenced by environmental factors. Longitudinal research, which follows large numbers of participants over multiple years, allows for the detection of changes over time through repeated examinations, such as blood tests, body measurements, and health questionnaires.

Previous Research and Future Prospects

Data from these cohorts have already been used to study the contribution of common genetic variants on phenotypes ranging from childhood obesity to parental nurturing behaviors and anxiety and depression. For instance, researchers found that a genetic variant in a gene called MC4R is associated with increased weight across childhood. Studies like this could help design effective weight management interventions and change the way society views obesity.

The team has made the anonymized data as accessible as possible to approved researchers, including drafting a data note and other materials to help support its use by those who are less familiar with large-scale sequencing data. In the coming months, this DNA sequence data resource will be expanded to encompass all participants in these cohorts as well as additional cohorts.

Conclusion

The release of high-resolution DNA sequencing data for 37,000 children and parents is a monumental achievement that will drive more discoveries and genetic research that could benefit human health. By providing researchers with access to this valuable resource, the scientific community can continue to explore the intricate relationship between genetics and environmental factors, ultimately leading to a better understanding of human health and development.
