Patients, scientists and advocates celebrate £3.2m funding for largest ever ME/CFS DNA study

Professor Chris Ponting co-leads the project on behalf of the MRC Human Genetics Unit. DecodeME, which launches today, is the world’s largest genetic study into myalgic encephalomyelitis (ME), also known as Chronic Fatigue Syndrome: June 2020

Decode Me

Despite its high cost to patients, the economy, the NHS and society, very little is known about the causes of ME, also diagnosed as chronic fatigue syndrome (CFS, or ME/CFS), including how to treat it effectively.

Now, thanks to £3.2 million funding, awarded jointly by the Medical Research Council and National Institute for Health Research, work can begin on DecodeME, the ME/CFS DNA study that hopes to reveal the tiny differences in a person’s DNA that may affect their risk of developing ME/CFS, and the underlying causes of the condition.

DecodeME will look at samples from 20,000 people with ME/CFS, in the hope that the knowledge discovered will aid development of diagnostic tests and targeted treatments.

ME/CFS affects an estimated 250,000 people in the UK, of all ages, and from all social and economic backgrounds. Post-exertional malaise, an adverse reaction to levels of exertion that many might consider trivial, is often considered to be the defining symptom - this can leave patients suffering from symptoms including extreme levels of fatigue, pain, inability to process information, and light and noise sensitivities. One in four people with ME/CFS are so severely affected they are house- and frequently bed-bound.

Partnering with the MRC Human Genetics Unit at the University of Edinburgh and the London School of Hygiene and Tropical Medicine, it’s being led by the ME/CFS Biomedical Partnership. This collaboration of researchers, people with ME/CFS, carers and advocates has grown out of the UK CFS/ME Research Collaborative (CMRC), established in 2013 by Prof Stephen Holgate, MRC Clinical Professor of Immunopharmacology at the University of Southampton.

People with ME/CFS across the UK will be asked to volunteer to take part in DecodeME, which they can do from home, confirming they meet the selection criteria via a patient questionnaire already being used by the CureME Biobank. Participants will be mailed a collection kit and asked to send back a saliva or 'spit-and-post' sample. These will be compared with samples from healthy controls.

The samples will enable the Partnership to undertake the world’s largest genome-wide association study (GWAS) of ME/CFS. Such studies have already helped to uncover the biological roots of many other complex diseases, including the identity of genes involved in Type II Diabetes, and the microglia (immune cells of the brain) that play a key role in Alzheimer’s Disease.

The study is scheduled to begin in September, with recruitment of participants from March 2021. Anyone with ME/CFS aged 16 years or over who wants to take part in the DecodeME study can register their interest now: www.decodeme.org.uk

 

Our focus will be on DNA differences that increase a person’s risk of becoming ill with ME/CFS. We chose to study DNA because significant differences between people with, and without, ME/CFS must reflect a biological cause of the illness. It is our hope that this study will transform ME/CFS research by injecting much-needed robust evidence into the field.

Simply put, we cannot do this without the determination and support of people with ME/CFS. Recruiting the 20,000 people we need is challenging – but absolutely achievable, by working in partnership with the CureME Biobank, charities, patient advocates, local support groups and others. People with ME/CFS can register their interest right now on the DecodeME website.

This project is very significant in its scale and ambitions. It is one of the biggest studies into potential genetic connections to ME/CFS and I would like to congratulate Prof Chris Ponting and his colleagues on this award. It signals the shared commitment of funders, researchers and patients to work together to gain new insights into ME/CFS.
