Rare large homozygous CFTR gene deletion in an Iranian patient with cystic fibrosis

Figure 1 Pedigree of a family of a 16-year-old boy with cystic fibrosis, showing the three transmembrane conductance regulatory alleles transmitted to the sibs. Allele 1 carries the deletion of exons 4 to 10; alleles 2 and 3 are distinguishable by the different numbers of TG associated to the polypyrimidine tract in intron 8.
