Summary

This study looks at how blood phenylalanine (Phe) levels affect thinking, emotions, and daily functioning in 30 adults with PKU. Researchers want to understand why some patients with high Phe levels have no major problems, while others do. The goal is to move toward personalized treatment recommendations instead of one-size-fits-all blood level targets.
