Scheme will enable siblings and children of those with fatal condition to know if they are likely to develop it themselves
Relatives of people with motor neurone disease are being offered genetic tests that will tell them if they are likely to also get the fatal neurological condition.
Siblings and children of the approximately 5,000 people in Britain with MND will be able to access a test that will identify if they have any of the more than 40 genes associated with the disease.
