Changes in these genes cause rare conditions in which Facial tics 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.

| ATP1A2ATPase Na+/K+ transporting subunit alpha 2 | Often (30–79%) | In 1 condition |
| CACNA1Acalcium voltage-gated channel subunit alpha1 A | Often (30–79%) | In 1 condition |
| GABRA1gamma-aminobutyric acid type A receptor subunit alpha1 | Often (30–79%) | In 1 condition |
| GABRG2gamma-aminobutyric acid type A receptor subunit gamma2 | Often (30–79%) | 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.
