Quizplus · Accepted Answer

PKU is linked to low levels of dopamine in the brain. This is because individuals with PKU are unable to break down phenylalanine, which can accumulate in the blood and compete with other amino acids for transport into the brain. This results in reduced levels of tyrosine, which is a precursor for dopamine synthesis.
