Clarification of the risk for venous thrombosis associated with hereditary protein S deficiency by investigation of a large kindred with a characterized gene defect

Article Abstract:

Persons deficient for protein S due to a genetic mutation appear to be at greater risk for developing deep venous blood clots. Protein S helps regulate the anticoagulation process. Deep venous blood clot risk was analyzed in 122 members of a family that had 44 individuals with the protein S defect. Those carrying the mutation were 11.5 times more likely to develop a deep venous blood clot compared to those not carrying the mutation, even after controlling for weight and smoking history. Protein S blood levels were a distinguishing factor between those with the defect and those without the defect.

The frequency of genes for hemochromatosis in patients attending a health appraisal clinic

Article Abstract:

Measuring blood levels of iron may not detect all people who have a gene mutation predisposing them to hemochromatosis. Hemochromatosis is a genetic diseased that causes iron deposits in various organs. In a study of 10,198 people, most of those with the gene mutation would have been missed by the usual blood tests.

Mutations of the angiotensinogen gene and the risk for heart disease and stroke

Article Abstract:

The M235T and the T174M mutations in the gene for angiotensinogen do not appear to increase the risk of heart disease or stroke, either alone or together. Angiotensinogen is a protein in the body that can affect blood pressure.
