4 genes linked to Fused labia majora

Changes in these genes cause rare conditions in which Fused labia majora 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
FDXRferredoxin reductase	Always	In 1 condition
PORcytochrome p450 oxidoreductase	Often (30–79%)	In 2 conditions
ARandrogen receptor	Sometimes (5–29%)	In 1 condition
NR5A1nuclear receptor subfamily 5 group A member 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.
