In 2016 and 2017, Michael and Laura's daughters died soon after being born with a rare genetic condition.
Michael said: 'the doctors obviously began to realise that it was possibly something genetic and that's when we were introduced to the 100,000 Genomes Project… and that changed everything.'
For more than ten years the 100,000 Genomes Project has been tracing and comparing the genomes of tens of thousands of patients with rare diseases and their relatives.
