DecodeME will only recruit participants in the UK so, only those with a UK postcode can join the study. There may, however, be scope in the future to expand the study outside of the UK or for replication studies to be conducted in other territories.


We hope to find a way for everyone who wants to take part to do so in future, and if you register your interest, we’ll keep in touch.
