Pyruvate Dehydrogenase Complex Deficiency Overview

Pyruvate dehydrogenase complex deficiency is a heterogeneous mitochondrial disorder caused by pathogenic variants affecting the pyruvate dehydrogenase complex, impairing conversion of pyruvate to acetyl-CoA and producing lactic acidosis, cellular energy deficiency, and variable neurological disease. The phenotype ranges from severe early-onset encephalopathy and seizures to milder later-onset presentations. There is currently no approved curative therapy, and management relies primarily on ketogenic diet therapy, which provides ketone-derived fuel downstream of the defective metabolic step, together with genotype- and manifestation-specific interventions such as thiamine, seizure treatment, and supportive rehabilitation. A 2026 global clinical-practice review found ketogenic therapy to be widely used, with reported benefits extending beyond seizure control to development, function, and cognition. Research is now expanding toward approaches that directly improve energy metabolism, including a recruiting pediatric trial of triheptanoin for primary-specific PDC deficiency. In parallel, gene-replacement strategies are advancing preclinically: a 2026 study using a neurotropic AAV-F vector delivering human PDHA1 improved survival, PDH activity, metabolic abnormalities, and brain pathology in a Pdha1-deficient mouse model. These findings support the potential of genetic restoration but remain far from human clinical validation. For stakeholders, PDCD represents a high-value rare-metabolic opportunity where the key challenge is moving beyond metabolic bypass toward durable restoration of PDC function and prevention of irreversible neurological injury.
