Variegate porphyria: identification of a nonsense mutation in the protoporphyrinogen oxidase gene.

Abstract excerpt

The porphyrias are disorders of porphyrin metabolism that result from inherited or acquired aberrations in the control of the heme biosynthetic pathway. Variegate porphyria is characterized by a partial reduction in the activity of protoporphyrinogen oxidase. In this study, we identified the first nonsense mutation in a family with variegate porphyria. The mutation consisted of a previously unreported G-to-T...
