Traits linked to ENO3

enolase 3

The Human Phenotype Ontology links 8 traits to ENO3, by body system: features seen in people with one of the gene's rare conditions.

Laboratory abnormality

Trait	How often it is seen
Reduced muscle enolase activity	Always
Elevated creatine kinase after exercise	Very often (80–99%)
Increased muscle glycogen content	Often (30–79%)
Exercise-induced myoglobinuria	Sometimes (5–29%)
Elevated blood creatine phosphokinase	Not recorded

Constitutional symptom

Trait	How often it is seen
Decreased ability to exercise	Very often (80–99%)
Muscle ache	Often (30–79%)

Abnormality of the musculoskeletal system

Trait	How often it is seen
Exercise-induced rhabdomyolysis	Very often (80–99%)

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.
