Changes in these genes cause rare conditions in which Hypnagogic hallucination 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 |
|---|---|---|
| HCRThypocretin neuropeptide precursor | Always | In 2 conditions |
| CTSHcathepsin H | Often (30–79%) | In 1 condition |
| DNMT1DNA methyltransferase 1 | Often (30–79%) | In 1 condition |
| HLA-DQB1major histocompatibility complex, class II, DQ beta 1 | Often (30–79%) | In 1 condition |
| HLA-DRB1major histocompatibility complex, class II, DR beta 1 | Often (30–79%) | In 1 condition |
| MOGmyelin oligodendrocyte glycoprotein | Often (30–79%) | In 2 conditions |
| P2RY11purinergic receptor P2Y11 | Often (30–79%) | In 1 condition |
| TNFSF4TNF superfamily member 4 | Often (30–79%) | In 1 condition |
| ZNF365zinc finger protein 365 | Often (30–79%) | In 1 condition |
| TRANK1tetratricopeptide repeat and ankyrin repeat containing 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.
