An urge to move the legs especially at rest. Heritability ~60%; family history significantly increases risk.
How Genetic Is Restless Legs Syndrome?
Restless Legs Syndrome involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 60%, though no single gene determines outcome on its own.
Key genes associated with Restless Legs Syndrome: BTBD9 MEIS1 MAP2K5. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
