Changes in these genes cause rare conditions in which Alien limb phenomenon 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 |
|---|---|---|
| ATP1A2ATPase Na+/K+ transporting subunit alpha 2 | Sometimes (5–29%) | In 1 condition |
| CACNA1Acalcium voltage-gated channel subunit alpha1 A | Sometimes (5–29%) | In 1 condition |
| PRRT2proline rich transmembrane protein 2 | Sometimes (5–29%) | In 1 condition |
| SCN1Asodium voltage-gated channel alpha subunit 1 | 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.
