Figure 1From: Partial protoporphyrinogen oxidase (PPOX) gene deletions, due to different Alu-mediated mechanisms, identified by MLPA analysis in patients with variegate porphyriaPedigrees of VP families carrying partial PPOX deletion. Pedigrees of the five families carrying partial PPOX deletion with DNA results and markers for biochemical symptoms. In families A-D affected members carry an exon 5–6 deletion. In family E the patient carries an exon 5–9 deletion. Members in family A-D for whom neither biochemical nor genetic investigation were performed are omitted for simplification.Back to article page
