    ### Instruction:
    Is restless legs syndrome inherited ?
    ### Response:
    The inheritance pattern of restless legs syndrome is usually unclear because many genetic and environmental factors can be involved. The disorder often runs in families: 40 to 90 percent of affected individuals report having at least one affected first-degree relative, such as a parent or sibling, and many families have multiple affected family members.
