Our DNA contains 3 billion letters of code: our genome. Almost 99.8% is the same for everyone, but in the remaining 0.2% there are differences that can sometimes be harmful. With genomic medicine we can have our DNA analysed to look for these differences to inform and personalise our healthcare. Genomics England’s vision is to support the NHS to make genomic medicine available to every patient, whilst enabling researchers to improve our understanding of diseases.
