One of the most pressing problems in medicine is multifactorial diseases, i.e., diseases that have many causes in their genesis and as a result from the joint action of unfavorable environmental conditions and a number of genetic factors. This group of diseases includes arterial hypertension, ischemic heart disease, atherosclerosis, rheumatoid arthritis, schizophrenia, peptic ulcer, bronchial asthma, psoriasis, atherosclerosis, etc. Due to the complexity of the etiology and pathogenesis of such diseases, their study and diagnosis is much more difficult than monogenic [1,2,3,4].
