Changes in these genes cause rare conditions in which Horner syndrome 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 |
|---|---|---|
| TM2D3TM2 domain containing 3 | Always | In 1 condition |
| ALKALK receptor tyrosine kinase | Sometimes (5–29%) | In 1 condition |
| HACE1HECT domain and ankyrin repeat containing E3 ubiquitin protein ligase 1 | Sometimes (5–29%) | In 1 condition |
| LIN28Blin-28 RNA binding posttranscriptional regulator B | Sometimes (5–29%) | In 1 condition |
| LMO1LIM domain only 1 | Sometimes (5–29%) | In 1 condition |
| MYCNMYCN proto-oncogene, bHLH transcription factor | Sometimes (5–29%) | In 1 condition |
| PHOX2Bpaired like homeobox 2B | Sometimes (5–29%) | In 1 condition |
| KIF1Bkinesin family member 1B | 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.
