A novel mutation in erythropoietic protoporphyria: an aberrant ferrochelatase mRNA caused by exon skipping during RNA splicing.
Division of Pediatric Hematology, Columbia University College of Physicians and Surgeons, New York, NY 10032.
An aberrant ferrochelatase mRNA lacking exon 10 was found in a patient with erythropoietic protoporphyria (EPP). In her genomic DNA an A-->T transversion at position -3 of the donor site of intron 10 appeared to be responsible for the exon skipping. Both the patient and her sister were heterozygous for this mutation.
