Trait
Positive Phalen test
The Phalen maneuver is performed by having the patient hold both wrists in complete and forced flexion (pushing the dorsal surfaces of both hands together) for 30-60 seconds. This can increase the pressure in the carpal tunnel. The test is positive (abnormal) if the patient experiences characteristic symptoms of carpal tunnel syndrome (pain and paresthesias along the distribution of the median nerve, i.e., thumb, index finger, and middle finger).

Changes in these genes cause rare conditions in which Positive Phalen test 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 |
|---|---|---|
| COMPcartilage oligomeric matrix protein | Always | 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.
