PK deficiency is caused by an inherited mutation in the PKLR gene, which can cause a deficit in energy within the red blood cell, as evidenced by lower PK enzyme activity, a decline in levels of adenosine triphosphate (ATP), which is responsible for storing and transferring energy in cells, and a build-up of certain metabolites.
Understanding Pyruvate Kinase Deficiency
What is pyruvate kinase deficiency?
Pyruvate kinase (PK) deficiency is a rare disease caused by inherited mutations in the PKLR gene, which can cause a deficit in energy and shortened lifespan for red blood cells. People with PK deficiency can experience a range of signs and symptoms, including anemia, debilitating fatigue, exercise intolerance, jaundice, memory loss and difficulty concentrating.
