Dangerously Thin: A Case Study on the Genetic Code At 65 years old, Henry Blake was in excellent health and enjoying his first year of retirement. Upon returning from his dream trip to the Great Barrier Reef in Australia, he noticed that his left leg was swollen just inferior to the knee. He already had scheduled an appointment for a complete physical, so he knew that in a few days he would be able to have his physician look at his leg.

A DVT was confirmed by the Doppler ultrasonography results (a test that uses sound to create images of blood flow). Dr. Strickland placed Henry on a “blood thinning” drug called warfarin, which works by preventing clots from forming. Henry returned to his retirement plans but quickly found himself back in Dr. Strickland’s office after suffering from frequent nose bleeds. A laboratory test called an INR (International Normalized Ratio) was performed. This test measures the time it takes for blood to clot and compares it to an average. The test revealed that the time it took for Henry’s blood to clot was well above what would be expected for the dose of warfarin that he had been placed on. Dr. Strickland immediately
