Living with Hereditary geniospasm
A movement condition that causes episodes of trembling in the chin and lower lip.
Understanding Hereditary geniospasm
Episodes can last from a few seconds to hours. They may happen on their own or be set off by stress. They usually start in infancy or childhood and tend to happen less often with age.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Shaking of the chin (chin myoclonus)
- Trembling of the lower lip
- Episodes lasting seconds to hours
- Episodes set off by stress
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
