Enzyme estimations are invariably carried out using synthetic chromogenic or fluorogenic substrates, which are structurally very simple as compared to the natural substrates. A defective enzyme resulting from mutation in the structural gene loses its activity on the natural substrates, leading to a genetic disease. Such an enzyme, at times, may still retain substantial catalytic activity on the synthetic substrate. If the enzyme activity falls within the normal range, the situation poses a problem in the diagnosis of the patient. To circumvent this situation, we have invented a novel approach which has enabled us to arrive at an unambiguous, definitive diagnosis of patients. Our novel approach will be presented here.
