Question

Quizplus · Accepted Answer

PKU stands for phenylketonuria, which is caused by a recessive gene that leads to the deficiency of the enzyme that converts phenylalanine into tyrosine. The accumulation of phenylalanine in the body can lead to intellectual disability and other complications. Diabetes insipidus is caused by the inability to produce or respond to antidiuretic hormone (ADH), Huntington's disease is a neurodegenerative disorder, hemophilia is a blood clotting disorder, and sickle cell anemia is a genetic blood disorder. None of these conditions are directly related to the deficiency of the phenylalanine to tyrosine enzyme conversion.
