What does PKU stand for in medical terminology?

PKU stands for Phenylketonuria, which is a genetic disorder that results in the inability of the body to metabolize the amino acid phenylalanine. This condition is due to a deficiency in the enzyme phenylalanine hydroxylase, leading to a buildup of phenylalanine in the body. If untreated, high levels of phenylalanine can cause severe intellectual disability and other neurological problems.

The importance of early detection through newborn screening programs is crucial, as it allows for dietary management to prevent the harmful effects associated with this condition. This understanding is key in both clinical and educational settings, as it highlights the significance of metabolic diseases in healthcare. The other options listed do not correspond to well-known medical terminology associated with PKU, reinforcing that the correct answer is the clinically relevant and recognized term.
