The CureHeart Project -Team of experts from UK, US and Singapore to design jab to save thousands of lives by rewriting DNA

Cardiomyopathies are “really common” and affected one person in every 250 around the world, said Prof Hugh Watkins, from the University of Oxford and lead investigator of the CureHeart project.

Scientists are to develop the world’s first cure for genetic heart conditions by rewriting DNA in a move hailed as a “defining moment” for cardiovascular medicine.

A global team of experts from the UK, US and Singapore are joining forces to design a jab in the arm for patients to save thousands of lives after being awarded a £30m grant from the British Heart Foundation.

According to Guardian, the team will use precision genetic techniques, called base and prime editing, in the heart for the first time to design and test the first cure for inherited heart muscle diseases, with the aim of silencing faulty genes. Animal studies have already shown the techniques work. These techniques are called base processing and primary processing,

“This is a defining moment for cardiovascular medicine,” said Prof Sir Nilesh Samani, the BHF’s medical director.

Hereditary heart muscle conditions are driven by different abnormalities in the heart but can cause sudden death or progressive heart failure. About 260,000 people have the condition in the UK, which can cause sudden death at any age.

Every week in the UK, 12 people under the age of 35 die of an undiagnosed heart condition, very often caused by an inherited heart muscle disease, also known as genetic cardiomyopathy.

All those with genetic cardiomyopathies have a 50/50 risk of passing faulty genes on to each of their children and, often, several members of the same family develop heart failure, need a heart transplant, or die at a young age.

Christine Seidman, a professor of medicine at Harvard Medical School in the US and co-lead of the CureHeart project, said the idea was to “fix the hearts” and revert them to more normal function. “Most of the mutations that we find in our human patients – and while there are vast numbers of them mutations– they all frequently will alter one single letter of the DNA code,” she said.

“That has raised the possibility that we could alter that one single letter and restore the code so that it is now making a normal gene, with normal function.”

“We may be able to deliver these therapies in advance of disease, in individuals we know from genetic testing are at extraordinary risk of having disease development and progressing to heart failure. Never before

have we been able to deliver cures, and that is what our project is about. We know we can do it and we aim to get started.”
