Emory University Studies Find Gene Linked to Night Leg Movement

BOSTON (Reuters) - Two studies released on Wednesday offer new evidence that inheritance plays a role in restless leg syndrome, an uncomfortable and sometimes painful feeling in the legs that can wreak havoc with sleep. Researchers reporting in the journal Nature Genetics say they have found three pieces of the human genetic code that are linked to RLS, giving more scientific backing to a condition sometimes derided as normal restlessness.
