Run for a reason

In the UK, there are thousands of children living with a rare and life-limiting disease for which there is no cure.

Children like Danny who has the rare disease, Hunter syndrome. Danny’s family are painfully aware that time with their youngest son will be cruelly cut short by this disease. But with your help we can fund vital research that can offer hope to families like Danny's that, in the future, lives can be saved.

We will lose our beautiful boy to Hunter syndrome. But any new hope is worth fighting for. So that families in the future don’t have to feel that the bottom is dropping out of their world.

Sally, Danny's mum
