Detection of C1744T polymorphism. Sequencing of exon 12 of the HIF-1α detected a heterozygous base change of C to T at nucleotide 1744 in 8 patients (Figure 1B) when compared to the normal sequence (Figure 1A). One patient, D1, was homozygous for this base change (Figure 1C). The position of the mutation is indicated by an arrow. Bases are as follows: G = black; A = green; T = red; C = blue. The C1744T mutation destroys the restriction site for Tsp 45I enzyme and the normal exon 12 PCR product is restricted in the presence of this enzyme into 4 fragments of 213, 156, 139 and 92 bp; in the presence of the C1744T mutation the 156 and 139 bp fragments are replaced with one of 295 bp. (Figure 1D). M1: 100 bp DNA ladder; M2: 25 bp ladder; 1: C1744 control individual; 2: heterozygous individual for C1744T polymorphism; 3: individual D1 homozygous for C1744T polymorphism.
