A novel point mutation (Val 297-->Met) in the serine proteinase domain of protein C in a patient with both venous and arterial thromboembolic disease.
A novel heterozygous GTG-->ATG (Val 297-->Met) substitution was detected in an individual with probable inherited protein C deficiency and both venous and arterial thrombotic disease. The lesion occurs in a highly conserved residue within the serine protease domain. In a molecular model of protein C, Met 297 makes unfavourable interactions with neighbouring residues suggesting that the mutant protein is unable to adopt a stable/functional conformation.
