    Primary pyruvate dehydrogenase complex deficiency is caused by mutations in genes encoding its component proteins, particularly the X-linked PDHA1 gene.

  • 2

    Animal models, especially mouse models, replicate cerebral abnormalities seen in PDC deficiency and help investigate cellular proliferation and differentiation.

  • 3

    Mouse models are valuable for assessing the effects of dietary and drug treatments on PDC deficiency and understanding its role in carbohydrate metabolism.

  • 4

    Approximately 80% of PDC deficiency cases are linked to mutations in the PDHA1 gene, with a heterogeneous clinical presentation including lactic acidosis.

  • 5

    The creation of missense mutations in animal models is essential for exploring genotype-phenotype relationships in PDC deficiency.
