Consider the specific case:
Since you mentioned PKU patients, you might want to use a word that relates to the specific metabolic disorder, such as:
* Had a characteristic "mousy" odor: PKU is associated with a distinctive "mousy" smell due to the buildup of phenylalanine in the body.
Ultimately, the best word to use will depend on your specific needs and the specific context of the sentence.
