Quizplus · Accepted Answer

PKU is an inborn error of metabolism, specifically a genetic disorder in which the body cannot properly break down an amino acid called phenylalanine. If left untreated, phenylalanine can build up in the blood and cause severe cognitive impairment and other health problems. While it is caused by a genetic defect, it is not a chromosomal abnormality or infection, and is not related to environmental toxins.
