Simulations were performed using non-genetics and genetics-based nomograms for typical AF and VTE patients harbouring variable number of variant alleles. The genotype of zero-variant patients is VKORC1G/G-CYP2C9 *1/*1. Patients carrying 1 variant allele have one of the following genotype combinations: VKORC1G/A-CYP2C9 *1/*1, VKORC1G/G-CYP2C9 *1/*2, or VKORC1G/G-CYP2C9 *1/*3. Patients carrying 2 variant alleles have one of the following genotype combinations: VKORC1A/A-CYP2C9 *1/*1, VKORC1G/A-CYP2C9 *1/*2, VKORC1G/A-CYP2C9 *1/*3, or VKORC1G/G-CYP2C9 *2/*2. Patients carrying 3 variant alleles have one of the following genotype combinations: VKORC1A/A-CYP2C9 *1/*2, VKORC1A/A-CYP2C9 *1/*3, VKORC1G/A-CYP2C9 *2/*2, or VKORC1G/A-CYP2C9 *2/*3. Patients carrying 4 variant alleles have one of the following genotype combinations: VKORC1A/A-CYP2C9 *2/*2, or VKORC1A/A-CYP2C9 *2/*3. AF, atrial fibrillation; VTE, venous thromboembolism.
