DNA Repair Gene Polymorphism and the Risk of Mitral Chordae Tendineae Rupture

Figure 1

Genotypes were generated from 402 bp PCR product acquired from 9 individuals using specific primers after digestion with PvuII restriction enzyme. The lanes were as follows: M: DNA ladder; lanes 1 and 7: CC genotype, homozygote variant; lanes 2 and 8: AA genotype, homozygote wild type; lanes 3, 4, 5, 6, 9, and 10: AC genotype; heterozygote.
