Summary

Also called
Flared nasal alae
Body system
Abnormality of head or neck

11 genes linked to Flared nostrils

Changes in these genes cause rare conditions in which Flared nostrils 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.

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.
