What is an inborn error of metabolism?

The food we eat has three main components, protein, carbohydrate and fat.  The body is designed to be able to very efficiently utilise each of these food components for a wide range of purposes, including growth, repair and normal functioning of cells in all body organs, and the provision of energy for the body’s needs.

Every one of these processes occurs as a result of a complex series of specific chemical reactions, and each one of those reactions is under the control of a specific specialised protein, called an enzyme.  In addition, specific enzymes regulate the clearance of the waste products that build up as a result of these chemical processes.

If there is a mistake (usually genetic in origin) in a specific enzyme, this can disrupt key chemical reactions or lead to the accumulation of potentially toxic waste products, with potentially catastrophic effects to the body.  These genetic mistakes in enzyme pathways are collectively known as inborn errors of metabolism or genetic metabolic disorders.

For many of these inborn errors there are diet-based treatments available, aiming to bypass the metabolic block or to restrict the accumulation of toxic waste products.  The information available at the Nutriton4Me website is designed to provide you with information about inborn errors of metabolism for which diet based therapies are available.
