Changes in these genes cause rare conditions in which Underdeveloped labia 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 |
|---|---|---|
| KAT6Blysine acetyltransferase 6B | Always | In 1 condition |
| TOP2BDNA topoisomerase II beta | Always | In 1 condition |
| PORCNporcupine O-acyltransferase | Very often (80–99%) | In 2 conditions |
| CCNQcyclin Q | Often (30–79%) | In 2 conditions |
| CHD7chromodomain helicase DNA binding protein 7 | Often (30–79%) | In 2 conditions |
| FZD2frizzled class receptor 2 | Often (30–79%) | In 1 condition |
| HNRNPRheterogeneous nuclear ribonucleoprotein R | Often (30–79%) | In 1 condition |
| SEMA3Esemaphorin 3E | Often (30–79%) | In 1 condition |
| SMARCA2SWI/SNF related BAF chromatin remodeling complex subunit ATPase 2 | Sometimes (5–29%) | In 1 condition |
| ARandrogen receptor | Not recorded | In 1 condition |
| ORC4origin recognition complex subunit 4 | Not recorded | In 1 condition |
| PORcytochrome p450 oxidoreductase | 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.
