 (fĕn′əl-kēt′n-o͝or′ē-ə, -yo͝or′-, fē′nəl-)
n. Abbr. PKU
A genetic disorder in which the body lacks the enzyme necessary to metabolize phenylalanine to tyrosine. Left untreated, the disorder can cause brain damage and progressive intellectual disability as a result of the accumulation of phenylalanine and its breakdown products.

[phenylketone, the class of organic compounds including phenylpyruvic acid, a breakdown product of phenylalanine that is abnormally abundant in the urine of those having the disorder (phenyl + ketone) + ur(o)- + -ia.]
