GENETIC screening could soon help identify people who have inherited a mutation linked to Parkinson’s disease.
In three studies published online in The Lancet this week, researchers show that a single mutation in one gene is to blame for 5 per cent of cases of Parkinson’s disease in families with a history of the disease. The same mutation is also responsible for 2 per cent of cases in families with no Parkinson’s history.
That makes the mutation, in a recently discovered gene called LRRK2, the most common yet linked to Parkinson’s. Other mutations in the same gene may also…
