A new DNA test found answers for over a third of patients whose muscle disease had no known cause. Muscle diseases can come from many kinds of gene changes. Some changes are tiny. Others are large or oddly shaped and hard to spot with older tests. Scientists built a test that reads long stretches of DNA at once. This lets it catch many different kinds of changes in a single pass. When tested on a group of patients, the new test worked better and gave clearer results than older methods.
