Changes in these genes cause rare conditions in which Dilated pupil 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 |
|---|---|---|
| ACTA2actin alpha 2, smooth muscle | Always | In 1 condition |
| MYH11myosin heavy chain 11 | Always | In 1 condition |
| MYL9myosin light chain 9 | Always | In 1 condition |
| OSTM1osteoclastogenesis associated transmembrane protein 1 | Always | In 1 condition |
| ATP1A2ATPase Na+/K+ transporting subunit alpha 2 | Often (30–79%) | In 1 condition |
| ATP1A3ATPase Na+/K+ transporting subunit alpha 3 | Often (30–79%) | In 1 condition |
| CACNA1Acalcium voltage-gated channel subunit alpha1 A | Often (30–79%) | In 1 condition |
| MT-TL2mitochondrially encoded tRNA-Leu (CUN) 2 | Often (30–79%) | In 1 condition |
| RHOBTB2Rho related BTB domain containing 2 | Often (30–79%) | In 1 condition |

| LOXL1lysyl oxidase like 1 | Not recorded | 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.
