Identification of the first variegate porphyria mutation in an indigenous black South African and further evidence for heterogeneity in variegate porphyria.

Abstract excerpt

Variegate porphyria is an autosomal dominant disorder of haem metabolism resulting from reduced levels of the penultimate enzyme in the pathway, protoporphyrinogen oxidase. Here we investigate the molecular basis of variegate porphyria in four non-R59W South African families. We report the identification of the first mutation in the protoporphyrinogen oxidase gene in a black South African individual (V290M). In...
