Every other day in the UK, a baby is born who may develop serious mitochondrial disease

Mitochondrial disease, or ‘mito’, is a rare, complex and difficult-to-diagnose genetic disorder that affects people in very different ways. It can affect any organ at any age, and often occurs in babies and young children. There is currently no cure, but we’re working hard to change that, and are the largest charitable funder of mitochondrial research in Europe.

Mitochondrial dysfunction has been identified as a key factor in other more common diseases including dementia, Parkinson's disease, epilepsy and cancer. The research we fund and support not only holds promise for individuals with mitochondrial disorders, but has the potential to benefit millions of others too.

That’s why, despite being a little-known disease, mitochondrial disease could be the key to some of the most important medical breakthroughs of our time.

All we want for Christmas... is a cure for mitochondrial disease

This Christmas, while families around the UK gather to unwrap presents and build memories together, baby Felix and his parents, Jess and Joe, are holding onto something far bigger.

Felix was diagnosed with mitochondrial disease – a devastating genetic condition that robs the body's cells of energy. For babies like Felix, the future, new treatments and a cure for mito can’t come fast enough.

At The Lily Foundation, our list is simple. All we want for Christmas is hope, research, answers and an eventual cure for this devastating condition. But we can’t get there without your support.

“Not a minute goes by when we don’t think of Connie”

For Kerry and Ryan, Baby Loss Awareness Week has always held special significance. A midwife for over 14 years, Kerry’s supported countless families through pregnancy, birth and loss. But last year, the week took on an entirely different meaning when the couple had to say goodbye to their baby daughter just four weeks and four days after she was born.
