5 genes linked to Lingual dystonia

Changes in these genes cause rare conditions in which Lingual dystonia is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.

Gene	How often it is seen	Conditions
GNALG protein subunit alpha L	Often (30–79%)	In 2 conditions
THAP1THAP domain containing 1	Often (30–79%)	In 2 conditions
ATP13A2ATPase cation transporting 13A2	Sometimes (5–29%)	In 1 condition
NGLY1N-glycanase 1	Sometimes (5–29%)	In 1 condition
VPS13Avacuolar protein sorting 13 homolog A	Sometimes (5–29%)	In 1 condition

How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
