How are saliva samples useful to the study, and to society as a whole?

Researchers can use DNA samples to look at whether parents and their children have certain types of genes. Studying the relative importance of genes and other factors helps researchers to understand differences in young people’s development, health, behaviour, growth and learning. For instance, recent research has identified genes associated with common allergies including pollen, dust-mite […]

What is a gene/DNA?

DNA (Deoxyribonucleic acid) is the genetic material in every cell of the body including blood, saliva, skin and hair. Everyone has DNA. We inherit our DNA from our parents. A gene is a section of DNA that contains the information our bodies need to make chemicals called proteins. In this way, they tell your cells […]

Why are you studying DNA?

We are studying DNA in order to look at the way genes (nature) and lifestyle (nurture) are related to feelings, behaviour, health, and development. It will help us to understand how nature and nurture work together. Although we all have very similar genes, there are many small variations. These different versions of our genes can […]

Where and how are the DNA samples kept?

Samples will be stored in a laboratory at the University of Bristol which is licensed by the Human Tissue Authority. Access to laboratory and sample areas is restricted to authorised personnel. Samples are stored in freezers covered by a 24 hour alarm system in case of freezer breakdown. Names and addresses are not attached to samples.

Why did you collect DNA from both biological parents?

We want to learn more about the influence of parents’ DNA on their children. An important aim of Child of the New Century is to look at children’s genes and their environment to see how they interact to affect health and development. Each child’s genes come from both their mother and father, so the value […]

Will we get any results from the DNA samples?

We will not be able to provide you with the results of genetic testing.  The tests that will be done on your DNA are for research purposes, and are not the same as clinical genetic tests. The results cannot be used for individual diagnosis. As such, we will not routinely feed back your individual results, […]

How will my DNA be used?

Your DNA will be used for research purposes only. It could be used by researchers who work in the commercial sector (e.g. a private company). Organisations which want to use the DNA samples to look at particular genes will have to apply for permission to an independent committee which oversees access to the samples. Researchers […]
