Restless legs syndrome (RLS) is a common sleep-related disorder for which the underlying biological pathways and genetic determinants are not well understood. The genetic factors so far identified explain less than 10% of the disease heritability. The first successful genome-wide association study (GWAS) of RLS was reported in 2007. https://www.roneverhart.com/OTTO-CAP-5-Panel-Mid-Profile-Mesh-Back-Trucker-Hat-OTTO-32-285/
