Molecular defects in erythropoietic protoporphyria with terminal liver failure.

Abstract:

:We identified two additional mutations in the ferrochelatase gene in two Swiss patients with erythropoietic protoporphyria (EPP). Ferrochelatase cDNA from patients was amplified by the polymerase chain reaction (PCR) and subjected to mutation analysis by sequencing PCR products either directly or after subcloning. The first patient, who underwent liver transplantation because of terminal liver failure, was identified as having a single point mutation (C to T) at nucleotide 175 that resulted in a Gln to stop codon conversion in one allele of the gene. In the second case, in which the patient has so far no liver involvement, a two-base deletion (T899G900) was found in one allele. Frameshift as a result of the deletion creates a stop codon. This study presents two new genotypes of EPP, including one with liver failure, a rare and fatal form of EPP.
