We have collected blood samples from about 4,500 volunteers from different rural regions throughout the UK. DNA has been prepared from these and over a million genetic markers have been examined in about 3,000 of our samples so far.

This work is ongoing. We are still recruiting to the project and to try and make sure that the sample is representative of the area throughout the ages, we are looking for people whose parents and grandparents were all born in the same locality.

If you can trace all your grandparents to the same local area, we would like to hear from you. Ultimately, we would require about forty five minutes of your time to fill in a couple of questionnaires, a consent form, do some simple smell and taste tests, have photographs and skin color measurements taken and finally donate about 20ml of blood.
