Trait

Flat nasal alae

An abnormal degree of flatness of the Ala of nose, which can be defined as a reduced nasal elevation index (lateral depth of the nose from the tip of the nose to the insertion of the nasal ala in the cheek x 100 divided by the side-to-side breadth of the nasal alae).

HPO HP:0010649

8 genes linked to Flat nasal alae

Changes in these genes cause rare conditions in which Flat nasal alae 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.
