inborn error of metabolism

A newborn is screened for an inborn error of metabolism.

Definition

Noun: A genetic disorder present from birth, caused by a defect in a specific gene. This defect typically results in a missing or deficient enzyme, which is a protein that speeds up chemical reactions in the body. The lack of this enzyme disrupts normal metabolic processes—the complex set of life-sustaining chemical reactions—leading to the abnormal buildup or deficiency of specific substances. This can cause various health problems, intellectual disability, or organ damage.

Usage

This term is used in medical and scientific contexts to classify a group of specific hereditary conditions. It is a formal, technical term.

Examples: * Phenylketonuria (PKU) is a classic inborn error of metabolism where the body cannot process an amino acid called phenylalanine. * Early screening of newborns can help detect an inborn error of metabolism before symptoms appear. * The doctor explained that the child's symptoms were consistent with an inborn error of metabolism.
