Changes in these genes cause rare conditions in which Long penis 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 |
|---|---|---|
| PLCB4phospholipase C beta 4 | Always | In 1 condition |
| CYP11B1cytochrome P450 family 11 subfamily B member 1 | Often (30–79%) | In 2 conditions |
| ESCO2establishment of sister chromatid cohesion N-acetyltransferase 2 | Often (30–79%) | In 2 conditions |
| INSRinsulin receptor | Often (30–79%) | In 4 conditions |
| LHCGRluteinizing hormone/choriogonadotropin receptor | Often (30–79%) | In 1 condition |
| POLR3ARNA polymerase III subunit A | Often (30–79%) | In 1 condition |
| TBC1D7TBC1 domain family member 7 | Often (30–79%) | In 1 condition |
| AKT1AKT serine/threonine kinase 1 | Sometimes (5–29%) | In 1 condition |
| FGFR1fibroblast growth factor receptor 1 | Not recorded | In 1 condition |
| KCNH1potassium voltage-gated channel subfamily H member 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.
