Elevated levels of aldolase are detected in myotonic muscular disease, including: polymyositis and progressive muscular dystrophy. Elevated levels of this enzyme have been observed in acute coronary syndromes 1. This enzyme has been identified as a myositis biomarker, a muscle-wasting disease resulting in reduced muscle strength and fatigue 2. Testing this enzyme can be utilised as a marker in the differential diagnosis of muscle weakness as aldolase levels remain consistent where weakness is caused by neurological problems such as multiple sclerosis (MS) 3.
Aldolase is a glycolytic enzyme responsible for catalysing the conversion of fructose 1-6-diphosphate to glyceraldehyde 3-phosphate and dihydroxyacetone phosphate via the glycolysis metabolic pathway. This enzyme is present in all bodily cells, more commonly in the nucleus and cytoplasm. It has been identified as having three isoforms: A, B and C. Isoform A is found bound to the actin-containing filament of the cytoskeleton. By binding (reversible) to these filaments, aldolase aids in regulating cell contractions. The highest concentrations of this enzyme are present in the brain, liver and muscles 1.
