Abstract excerpt
The analysis of 750 mutations in the gene of blood coagulation factor IX has been made for 806 patients with haemophilia B. It has been found that 40% of all point mutations take place in 11 "hot spots", i.e., methylated CG sites, and are CG-->TG or CA transitions. Mechanism proposed explains the high rate of these transitions by m5C deamination during replicative DNA methylation and by mistakes of G/T-repair....
