Novel Deoxyguanosine Kinase Gene Mutations in the Hepatocerebral Form of Mitochondrial DNA Depletion Syndrome

Abstract

Deoxyguanosine kinase (DGUOK) gene mutations have been identified in the hepatocerebral form of mitochondrial DNA depletion syndromes. We report here clinical and laboratory features of 3 infants with novel DGUOK gene mutations, c.130G>A (Glu44Lys), c.493G>A (Glu165Lys), and c.707+3_6delTAAG.
