Inborn Errors of Metabolism
Inborn errors of metabolism (pronunciation: in-born er-rors of me-tab-o-lism) are a group of rare genetic disorders in which the body cannot properly turn food into energy. The term "inborn error of metabolism" was coined by a British physician, Sir Archibald Garrod (Archibald Garrod), in the early 20th century.

The term "inborn errors of metabolism" comes from the fact that these conditions are present from birth (inborn) and affect the body's metabolism. The word "metabolism" comes from the Greek word "metabole" which means change, referring to the chemical changes in the body that produce energy and sustain life.
