A pathogenic glutamate-to-aspartate substitution (D296E) in the pyruvate dehydrogenase E1 subunit gene PDHA1.

In a patient with fatal neonatal lactic acidosis due to pyruvate dehydrogenase deficiency, the only potential mutation detected was c.888C>G in PDHA1, the gene for the E1alpha subunit of the complex. This would result in a substitution of glutamate for aspartate (D296E). Pathogenicity of this minor alteration in amino acid sequence was demonstrated by expression studies. By comparing the mutant sequence with the known structures of the E1 components of pyruvate dehydrogenase and the closely related branched chain alpha-ketoacid dehydrogenase, an explanation for the profound consequences of the mutation can be proposed.[1]
