Abstract excerpt
Direct sequencing of the regions of the factor IX gene of likely functional significance was performed in four patients with severe hemophilia B. In two of the individuals, a transition at the dinucleotide CpG caused a nonsense mutation at arginine 333. In the other two individuals, a transition at CpG caused a nonsense mutation at arginine 29. Since these patients are all unrelated, as shown by differing alleles...
