A computer-implemented method for providing information for personalizing drug selection using individual genome sequence variations, comprising: determining one or more gene sequence variation information involved in the pharmacodynamics or pharmacokinetics of a predetermined drug or drug group on the basis of individual genome sequence information; calculating an individual protein damage score by using [Equation 2], wherein [Equation 2] is: S g v 1,..., v n = ∏ i = 1 n v i w i 1 / ∑ i = 1 n w i wherein Sg is the individual protein damage score of a protein encoded by a gene g, n is the number of target sequence variations for analysis among sequence variations of the gene g, v i is a gene sequence variation score of an i th gene sequence variation, and w i is a weighting assigned to the gene sequence variation score v i of the i th gene sequence variation; and calculating an individual drug score by using [Equation 4], wherein [Equation 4] is: S d g 1,..., g n = ∏ i = 1 n g i w i 1 / ∑ i = 1 n w i wherein S d is the individual drug score of a drug d, n is a number of proteins encoded by one or more genes involved in the pharmacodynamics or pharmacokinetics of the predetermined drug or drug group d, g i is a protein damage score of a protein encoded by one or more genes involved in the pharmacodynamics or pharmacokinetics of the predetermined drug or drug group d, and w i is a weighting assigned to the protein damage score g i of the protein encoded by one or more genes involved in the pharmacodynamics or pharmacokinetics of the predetermined drug or drug group d; and providing information for personalizing drug selection based on the calculation of the individual drug score. determining one or more gene sequence variation information involved in the pharmacodynamics or pharmacokinetics of a predetermined drug or drug group on the basis of individual genome sequence information; calculating an individual protein damage score by using [Equation 2], wherein [Equation 2] is: S g v 1,..., v n = ∏ i = 1 n v i w i 1 / ∑ i = 1 n w i wherein Sg is the individual protein damage score of a protein encoded by a gene g, n is the number of target sequence variations for analysis among sequence variations of the gene g, v i is a gene sequence variation score of an i th gene sequence variation, and w i is a weighting assigned to the gene sequence variation score v i of the i th gene sequence variation; and calculating an individual drug score by using [Equation 4], wherein [Equation 4] is: S d g 1,..., g n = ∏ i = 1 n g i w i 1 / ∑ i = 1 n w i wherein S d is the individual drug score of a drug d, n is a number of proteins encoded by one or more genes involved in the pharmacodynamics or pharmacokinetics of the predetermined drug or drug group d, g i is a protein damage score of a protein encoded by one or more genes involved in the pharmacodynamics or pharmacokinetics of the predetermined drug or drug group d, and w i is a weighting assigned to the protein damage score g i of the protein encoded by one or more genes involved in the pharmacodynamics or pharmacokinetics of the predetermined drug or drug group d; and providing information for personalizing drug selection based on the calculation of the individual drug score.
