This greatly genome [2]. Today, a reliable statistical relationship has been complicates the development of rations and increases their cost. established between the presence of certain varieties (alleles) of A methodology for the formation of target diets based on the fixed genes in relation to susceptibility to more than 150 multidimensional objects clustering method has been proposed. hereditary diseases [3]. The process of occurrence of a disease Clustering in the experimental group was carried out on the basis may be associated with disruptions in the functioning of of a calculation of the integral assessment of reliable risks of individual organs and systems and be a consequence of a developing decease conditions according to selected metabolic violation of nutritional status, which does not take into account processes. And genetic data of participants was taken into account. The use of the proposed method allowed reducing the the peculiarities of the genetic influence on the nutrient needs needed number of typical solutions of individual diets for the of the body. Thus, food products and food rations, designed to experimental group from 10 to 3. meet the corrected needs for food nutrients that take into account genetic characteristics of a particular organism, Keywords—Multidimensional objects clustering method; automatically prevent the adverse functioning of problem integral assessment of reliable risks; nutritional needs of the body; organs and systems [4-6]. personalized nutrition The use of statistical methods for analyzing medical I. INTRODUCTION information is currently relevant. With the development of technology, the sphere of their use is expanding and includes Modern studies of the human genome have allowed the the methods of information processing called Data Mining. identification of many genes responsible for metabolic processes, whose polymorphism plays a significant role in the One of the main effective and widely used methods of Data occurrence of metabolic disorders and the development of Mining in relation to large amounts of information is a diseases. Identifying the alleles of such genes that are present clustering method. The point of the method is in searching in humans helps to determine the risk factors of particular signs of similarity between objects in a particular subject area health disorders and to develop optimal measures that will 45 | P a g e www.ijacsa.thesai.org (IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 10, No. 2, 2019 and the subsequent merging of objects into subsets (clusters) processes and causing the risk of occurrence of certain diseases according to established signs of similarity. were selected as the most significant ones: biotransformation of xenobiotics, metabolism of vitamins, assessment of psycho- Data mining contains methods of detection, data collection, emotional status. as well as its intellectual analysis. Data Mining is a multidisciplinary field that emerged and develops on the basis Table 1 lists the controlled alleles of genes and of such sciences as applied statistics, pattern recognition, corresponding risks of hereditary multifactorial diseases for the artificial intelligence, database theory, etc. mentioned above metabolic processes. This study examined the effect of a limited list of gene Biotransformation of xenobiotics is a biochemical process panels on metabolic processes with the calculation of the during which substances transform under the action of various integral assessment of reliable risks for the development of enzymes of the body [9-17]. Its biological meaning is the disease conditions, and also proposed the application of the transformation of a chemical substance into a form suitable for multidimensional objects clustering method in order to form removal from the body. Four genes of the activation phase of diets for target groups of consumers. xenobiotics (CYP1A1*2B, *4, CYP2D6*3, *4, CYP2C9*2, *3 and CYP2C19*2) and four genes of the detoxification phase The task of clustering is due to the fact that in the case of (GSTT1, GSTM1, NAT2 and TPMT) were included in the mass (industrial) formation of rations, the problem of finding biotransformation panel under study. To assess the vitamin typical solutions arises. These solutions should be made for status of the organism, marker genes that indicate risks of target groups of consumers assigned to a particular cluster. It reducing the concentration of vitamins in the organism of the should be noted that clusters themselves are unknown in genome carrier (NBPF3 (ALPL), FUT2, BCMO1, APOA5) advance. Therefore, in order to accumulate information about were studied [18, 19]. To assess the psychoemotional status of clusters during scientific research, the clustering problem is participants in the experimental group, gene activities (DRD- solved and the method of their formation is worked out [7, 8]. 2A, SR (HTR2A)) responsible for the synthesis of serotonin II.
