Trait

Abnormality of the bridge of the nose

Clinical name: Abnormal nasal bridge morphology

Abnormality of the nasal bridge, which is the saddle-shaped area that includes the nasal root and the lateral aspects of the nose. It lies between the glabella and the inferior boundary of the nasal bone, and extends laterally to the inner canthi.

HPO HP:0000422

2 genes linked to Abnormality of the bridge of the nose

Changes in these genes cause rare conditions in which Abnormality of the bridge of the nose 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.

GeneHow often it is seenConditions
EBPEBP cholestenol delta-isomeraseOften (30–79%)In 1 condition
BCKDKbranched chain keto acid dehydrogenase kinaseSometimes (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.
