PKU carriers: How high phenylalanine affects the brain
Part of Brain & nervous system, Genetic & congenital clinical trials.
This study looks at how carrying one copy of the PKU gene might affect thinking and brain health in adults. It will help researchers understand if mild changes in a substance called phenylalanine can impact memory, focus, and brain scans.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 60 years old.
- You are a parent, sibling, or confirmed carrier of the PKU gene (meaning you have one copy but not the disease).
- OR you are in the non-carrier group and have no PKU in your family.
- Your body mass index (BMI) is 30 or less.
- You do not smoke or use nicotine products.
- You do not have a metal implant, pacemaker, or other MRI safety concern, and you are not pregnant or planning pregnancy.
- You do not have a major brain condition like multiple sclerosis, severe head injury, or Parkinson's disease.

This study tests whether a specific mix of large neutral amino acids (LNAAs) can help adults with classical PKU by lowering phenylalanine levels in the brain. It includes an MRI and PET scan to see how the treatment affects brain activity.
This study looks at how the brain ages in adults with PKU. It uses an MRI scan to compare brain changes between people with PKU and healthy volunteers.
This study looks at whether following specific care guidelines for phenylketonuria (PKU) leads to better metabolic control (blood phenylalanine levels) and better patient well-being. You may be asked to complete questionnaires and follow the study plan while receiving the usual PKU treatment your clinic recommends.
This study looks at how adults with phenylketonuria (PKU) or hyperphenylalaninemia (HMP) cope with daily life, emotions, and relationships, with input from a relative who lives with them. The goal is to better understand the challenges so care can be improved.
This study looks at whether checking phenylalanine levels at home more often helps people with classic PKU keep their levels in a healthy range. It may help you manage your diet and treatment more effectively.
This study looks at how a phenylalanine-restricted diet or certain PKU medicines affect gut health in children with PKU. It also includes healthy siblings or household members as a comparison group.
