SUMMARY: Identification of 3 genetic variants associated with essential tremor (ET).
OVERVIEW: ET is a neurological disorder characterized by involuntary shaking, especially of the hands, legs, and head. This occurs when one tries to use the affected muscles during voluntary movements such as eating and writing. This differentiates from conditions like Parkinson’s disease that causes shaking of resting muscles. This genome-wide association study identified 3 genetic variants that are associated with this condition by examining the genomes of over 9,000 individuals of European ancestry.
DID YOU KNOW? Physical therapy can help those affected by ET. In addition to exercises, the utilization of heavier versions of daily objects (silverware, pens, etc.) can help reduce the shaking movements. [SOURCE]
