Korea Biomedical Review: Researchers at Seoul National University Hospital have discovered a biomarker that causes restless legs syndrome.

The team discovered the protein after conducting a proteomic analysis using serum samples from seven RLS patients and six healthy controls. Proteomic analysis is a method of comprehensively studying proteins in vivo, identifying proteins that act on disease, and understanding their interactions.

Through the analysis, the team found eight unique proteins only observed in RLS patients.
