Genetic comparison of restless leg syndrome and essential tremor in a European population

Takeaway

  • When studied in a European population, there was no evidence of a causal relationship between restless leg syndrome (RLS) and essential tremor (ET).

Why this matters

  • This study disagrees with a previously published study in a Chinese population that indicated a genetic link between RLS and ET, suggesting there may be differences in these disorders due to ethnic background.
