Scientists on brink of cure for genetic heart disease in ‘defining moment’ for medicine

Scientists believe they are just a few years away from groundbreaking cure for genetic heart conditions which put 260,000 people each year in the UK at risk of sudden death.

Researchers have been awarded £30m to develop a cure for inherited heart muscle diseases which can kill young people “in the prime of their lives.”

The Cure Heart international research team has come together through the British Heart Foundation’s Big Beat Challenge.

One of the leads for the project, Professor Hugh Watkins said the reserach was an “once-in-generation opportunity to relieve families of the constant worry of sudden death, heart failure and potential need for a heart transplant.”

Professor Sir Nilesh Samani, medical director at the British Heart Foundation, said: “This is a defining moment for cardiovascular medicine. Not only could Cure Heart be the creators of the first cure for inherited heart muscle diseases by tackling killer genes that run through family trees, it could also usher in a new era of precision cardiology.”

Professor Hugh Watkins said his team believed they would be ready for clinical trials within five years

Using the BHF funding, the researchers aim to develop the first ever cures for inherited heart muscle diseases by rewriting DNA with the aim of editing or silencing faulty genes.

The team, made up of scientists from the UK, US and Singapore, has so far proven its approaches are successful in animals with cardiomyopathies and in human cells.

The aim is for the therapies to be injected into the arm and stop progression or potentially cure those living with genetic cardiomyopathies.

The technology could also be used to prevent the disease developing in family members who carry a faulty gene.

‘Life changing’

One patient with a heard condition which puts him at risk of cardiac arrest said the cure would be “life-changing”.

Max Jarmey, 27, was diagnosed with arrhythmogenic cardiomyopathy in his teens, just a few years after his father Chris died suddenly.

He was forced to give up sport after his diagnosis.

Mr Jarmey said: “I’m pretty mentally robust but the first six months following my diagnosis were incredibly difficult. It was horrible to be told I had a condition like ARVC at the age I was told, and then to be forced to quit something I loved.”

He now lives with an implantable cardioverter defibrillator (ICD), a device which shocks his heart back to normal rhythm, protecting him from cardiac arrest.

He said: “When I think about my future, the decision to have children and their future, Cure Heart could make that decision easier. My children might never have to suffer like I have with this condition. That is completely life-changing.”


Each week in the UK, 12 people under the ages of 35 die of undiagnosed heart conditions each year, often caused by an inherited heart muscle disease called genetic cardiomyopathy.

Around half of all heart transplants are needed because of cardiomyopathy and it is estimated around 260,000 people in the UK are impacted by these diseases.

Professor Hugh Watkins, from the Radcliffe Department of Medicine at the University of Oxford and lead investigator of Cure Heart, said: “This is our once-in-generation opportunity to relieve families of the constant worry of sudden death, heart failure and potential need for a heart transplant.

“After 30 years of research, we have discovered many of the genes and specific genetic faults responsible for different cardiomyopathies, and how they work. We believe that we will have a gene therapy ready to start testing in clinical trials in the next five years.”

Dr Christine Seidman at Harvard University and co-lead of Cure Heart, said: “Acting on our mission will be a truly global effort.

“We’ve brought in pioneers in new, ultra-precise gene editing, and experts with the techniques to ensure we get our genetic tools straight into the heart safely. It’s because of our world-leading team from three different continents that our initial dream should become reality.”
