Preferred Label : Restless legs syndrome, susceptibility to, 1;
Symbol : RLS1;
CISMeF acronym : RLS1;

Alternative titles and symbols : Acromelalgia, hereditary; Ekbom syndrome;
Description : Restless legs syndrome (RLS) is a neurologic sleep/wake disorder characterized by
uncomfortable and unpleasant sensations in the legs that appear at rest, usually at
night, inducing an irresistible desire to move the legs. The disorder results in nocturnal
insomnia and chronic sleep deprivation (Bonati et al., 2003). - Genetic Heterogeneity
of Restless Legs Syndrome RLS1 has been mapped to chromosome 12q. Other susceptibility
loci for RLS include RLS2 (608831) on chromosome 14q13-q31; RLS3 (610438) on chromosome
9p24-p22; RLS4 (610439) on chromosome 2q33; RLS5 (611242) on chromosome 20p13; RLS6
(611185) on chromosome 6p21; RLS7 (612853) on chromosome 2p14; and RLS8 (615197) on
chromosome 5q31.;
Inheritance : Autosomal dominant;
Laboratory abnormalities : Decreased CSF ferritin despite normal serum ferritin levels; Increased CSF transferrin despite normal serum transferrin levels;
