This study aims to better understand Pyruvate Dehydrogenase Complex Deficiency (PDCD), a condition that affects how your body uses carbohydrates for energy, especially in the brain. Researchers will collect information about your medical history, how current treatments like dietary supplements, medications, and the ketogenic diet have worked for you, and review your medical records. For some participants, advanced genetic testing will be performed to explore the genetic causes of PDCD. The goal is to improve our understanding of the disease, its symptoms, and how different treatments affect outcomes. You may be eligible if you have low Pyruvate Dehydrogenase Complex (PDC) activity in your cells or a known genetic change linked to PDCD. The study is currently ongoing, but its exact recruitment status is unclear.

Study design

This is an observational study, meaning researchers will collect information without providing any new treatments. It plans to include about 150 participants with PDCD.

What's involved

You would complete a questionnaire about your medical history and experiences with PDCD. Researchers will also review your medical records, and in some cases, perform advanced genetic testing.

Compensation

Not stated in the trial record.

Follow-up

Survival outcomes will be measured from birth until the last known date you were living at the time of data analysis.
