Trait
Abnormal peripheral nervous system structure
Clinical name: Abnormal peripheral nervous system morphology
A structural abnormality of the peripheral nervous system, which is composed of the nerves that lead to or branch off from the central nervous system. This includes the cranial nerves (olfactory and optic nerves are technically part of the central nervous system).

Changes in these genes cause rare conditions in which Abnormal peripheral nervous system structure 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.
